A Practical Guide for Collection Planning
Planning a new swimwear collection or looking for gaps in your current range? Understanding the main types of swimsuits makes it easier to compare shapes, coverage, and intended use, then build a more balanced product mix. From one-pieces and bikinis to tankinis, swim dresses, rash guards, and swim shorts, this guide shows the differences between the most common styles.
Types of Swimsuits at a Glance
Start with these six common swimsuit types and the main differences in shape, coverage, and use.
| Swimsuit type | How to recognize it | What it offers |
|---|---|---|
| One-piece swimsuit | One connected garment covers the torso. Necklines, straps, backs, legs, and sleeves vary. | A connected shape that ranges from classic and active styles to fuller-coverage designs. |
| Bikini | A separate top and bottom may be sold as a set, as separates, or both. | Flexible top-and-bottom combinations with varying support, rise, and coverage. |
| Tankini | A longer swim top is paired with a separate bottom. | More torso coverage while retaining a two-piece structure. |
| Swim dress | A dress-like swimsuit with a skirt layered over an inner brief or shorts. | A dress-inspired outline with added coverage at the hips or upper legs. |
| Rash guard set | A short- or long-sleeve top is paired with briefs, shorts, a skirt, or leggings. | More arm coverage and a choice of coordinating bottoms. |
| Swim shorts | A shorts-shaped bottom comes in a range of lengths, fits, waistbands, and linings. | Choices for pool, beach, surf, and casual use. |
One design may fit more than one label. For example, the same swimsuit can be one-piece, one-shoulder, and high-cut.
Types of Women’s Swimsuits
From one-pieces and bikinis to tankinis, swim dresses, and rash guard sets, you have a broad choice of shapes, coverage levels, and styling details.
One-Piece Swimsuit Styles
Changes to the neckline, straps, cut-outs, leg openings, and sleeves create many types of one-piece swimsuits.

Classic Tank One-Piece
Two shoulder straps and a clean, familiar outline define the classic tank. Scoop or square necklines, open or higher backs, and print changes give this dependable shape a fresh look. It works well as an everyday style for the pool or beach.
Strapless or Bandeau One-Piece
With no fixed shoulder straps, the bandeau creates a clean line across the chest. Removable straps give the wearer another way to style the suit. Depending on the design, cups, an underband, or other internal structure help the top stay in place.
Plunge or V-Neck One-Piece
The angled front of a V-neck may be shallow or deep, while a plunge extends farther down the chest. This difference lets you choose between a subtle neckline detail and a more open look for beach or resort wear.
One-Shoulder One-Piece
Covering one shoulder and leaving the other bare creates a strong asymmetric outline. A wide strap feels bolder than a narrow strap or tie. The neckline already gives the suit a focal point, even in a solid color.
Cut-Out One-Piece and Monokini
Cut-outs reveal selected areas at the waist, sides, front, or back. Small openings add detail; larger ones make a connected suit look closer to a two-piece. Some markets call these designs monokinis, but the term is not used consistently. Not every cut-out one-piece is a monokini.
High-Cut One-Piece
Higher leg openings create a longer-looking leg line and sit farther up the hips. Leg height and back coverage are separate choices, so a high-cut front may still have a fuller back.
Long-Sleeve One-Piece
Long sleeves add arm coverage to a connected suit. Necklines, zippers, and leg openings take the design from simple and sporty to more decorative. The shape suits surf, swim, or sunwear, although not every long-sleeve one-piece is a rash guard.
Bikini Top Styles
Bikini tops vary in neckline, cup shape, straps, and the amount of fabric below the bust. The same bottom can create a different look with each top, while the complete construction determines fit and support.

Haut de bikini triangle
Triangular cups create a simple, open shape. Sliding cups move along the lower tie, so their position and spread can be adjusted. Fixed triangles stay in place more consistently. The difference affects adjustability and how consistently the cups stay in position.
Scoop-Neck Bikini Top
Characterized by a rounded neckline, the scoop-neck top pairs easily with simple briefs or high-waisted bottoms. Narrow straps keep the outline light; wider straps and a cropped body move it in a sportier direction.
Halter Bikini Top
Halter straps run around the neck and leave the shoulders open. Tie straps allow some adjustment, whereas fixed bands or clasps hold a more defined shape. Support also depends on cup construction and strap width, not the neckline alone.
Bandeau or Strapless Bikini Top
The bandeau wraps across the chest without fixed shoulder straps. Straight, gathered, and twisted fronts change the look without changing the basic outline. Removable straps add flexibility, while the band and internal structure affect how securely the top stays in place.
Underwire Bikini Top
Wires beneath the cups help shape and support the bust. Neckline, cup coverage, and padding may range from open to fuller styles. The final fit comes from the cup, band, wire, and straps working together.
Longline Bikini Top
Extending farther below the bust, a longline top has the look of a cropped swim top and covers more of the upper torso. The longer body changes the silhouette, but it does not guarantee stronger bust support.
High-Neck Bikini Top
More fabric across the upper chest gives this top its higher neckline. Open backs, racerbacks, and varied armholes change the silhouette while keeping the front covered. It creates a sporty look without the length of a full swim top.
One-Shoulder Bikini Top
One strap and one bare shoulder form an asymmetric outline. Knots, gathers, or a wider shoulder panel provide enough detail to make the top stand out. A simpler bottom keeps attention on the neckline.
Bikini Bottom Styles
To compare bikini bottom types, look at waist height, side width, leg opening, and back coverage as separate features. A high waist, for example, does not tell you how much of the back is covered.

Classic Bikini Bottom
The classic bottom follows a brief-like outline without short legs or a skirt layer. It pairs with most bikini tops and works as a useful base style. Rise, side width, and back coverage still vary, so “classic” does not always mean full coverage.
High-Waisted Bikini Bottom
Rising toward or above the navel, this bottom covers more of the lower torso than a low-rise brief. It changes the proportion of a bikini, especially beside a smaller top. Back coverage may still be full or revealing.
Hipster Bikini Bottom
A hipster sits around the hips rather than the natural waist. Its sides are usually wider than those of a string bottom, giving it a broad, low waistband without the torso coverage of a high-waisted cut.
High-Cut Bikini Bottom
The leg openings sit higher at the hips, creating a sharper leg line. That line works with low-, mid-, or high-rise waists. Back coverage remains a separate decision, so high-cut does not automatically mean cheeky.
Cheeky, Brazilian, and Thong Bottoms
These names refer to lower-back-coverage cuts, but they do not form a universal scale.
- Cheeky: Part of the buttocks remains exposed, often through a narrower or curved back panel.
- Brazilian: The back is often narrow or tapered, although its shape may overlap with cheeky cuts in some markets.
- Thong: A narrow strip or panel leaves most of the buttocks exposed.
Clear back views are more reliable than the style names alone.
Tie-Side Bikini Bottom
Ties at the hips add a visible detail and may allow the sides to loosen or tighten. Decorative ties attached to fixed sides do not provide the same adjustment. The width of the sides and shape of the back also affect the finished look.
Boyshort Bikini Bottom
Short legs distinguish the boyshort from a brief and cover more of the hips or upper thighs. Some extend only slightly below the crotch; others look closer to fitted shorts. Either shape can be paired with a bikini or tankini top.
Skirted Bikini Bottom and Swim Skort
A skirted bottom layers a skirt over an inner brief. A swim skort uses shorts underneath instead. Skirt length and the inner garment affect coverage as well as comfort during movement.
Selling tops and bottoms separately allows customers to pair sizes, but it also creates more stock combinations to manage.
Tankinis
UN tankini pairs a longer swim top with a separate bottom. The top may finish near the waist or extend over the hips, providing more torso coverage than most bikinis. Briefs, shorts, and skirted bottoms each change the overall look. When pieces are sold separately, the top and bottom can be selected in different sizes.

Swim Dresses and Skirted Swimwear
The dress-like outline comes from a skirt that falls over the hips or upper thighs. Some swim dresses have an integrated one-piece or brief, while others pair a longer top with a separate bottom. A close-fitting skirt feels quite different from a flared shape, even at the same length.
Three-Piece and Coordinated Sets
Three-piece sets often add matching shorts, a skirt, or a rash guard to a bikini or tankini. The extra piece lets the wearer adjust the outfit for the activity or desired coverage. You may sell the pieces together, separately, or in both formats.
Burkinis and Modest Swimwear
UN burkini usually combines a longer top with swim pants and may include a separate or attached head covering. Top length, fit, and the number of pieces vary. Other modest swimwear uses similar combinations with more body coverage, so one fixed outfit does not define the category.
Rash Guard Sets and Swim Shorts
A sleeved rash guard paired with swim shorts forms a practical set for surf, pool, or beach use. Tops may fit close to the body or feel more relaxed. Bottoms range from short, fitted shapes to looser cuts with longer legs.
Types of Men’s Swimwear
Men’s swimwear styles range from close-fitting briefs and jammers to relaxed trunks and board shorts. Swim tops and connected suits add coverage for particular activities.

slip de bain
Close-fitting swim briefs leave most of the legs uncovered. Side width and waist height alter the appearance while preserving the compact shape. They suit swimming when a loose short is not wanted.
Swim Trunks and Shorts
short de bain homme and trunks usually have a relaxed fit and an elastic waistband. Leg length, drawstrings, pockets, and linings create the main variations for pool and beach wear. Mesh briefs, fitted inner shorts, and unlined designs also feel different against the body.
Swim Jammers
Jammers fit closely and extend down the thighs, often toward the knees. Their longer, fitted shape is familiar in swim training. Fabric and fit influence how freely the wearer can move.
Boardshorts
Designed with surfing and active beach use in mind, short de bain often have a fixed waistband and lace-up closure. Newer versions may add stretch fabric or elastic sections. Waistband construction, fabric, lining, and freedom of movement distinguish them more clearly than length alone.
Rash Guards and Swim Tops
Short or long sleeve swim tops pair with trunks, briefs, or board shorts. Rash guards commonly fit close to the body, while other swim tops feel looser. Sleeve length and body shape help match the top to its intended activity.
One-Piece Rash Guard Suits
This more specialized suit connects the top and bottom, usually with a zipper for access. The joined construction helps prevent a separate top from riding up. Sleeve and leg lengths vary with the intended use.
Types of Kids’ and Baby Swimwear
Kids and babies share many swimsuit shapes, but age changes the proportions, dressing access, and room needed for a swim diaper.

One-Piece Swimsuits and Sunsuits
One-piece designs join the top and bottom, with variations in straps, sleeves, and leg length. Sunsuits often cover more of the arms or thighs. These styles come in different designs for girls, boys, and babies, with proportions adapted to age and intended use. For babies, generous openings and easy access make dressing and diaper changes simpler.
Two-Piece Swimsuits
Bikinis and tankinis combine separate tops with briefs, shorts, or skirted bottoms. Kids’ tankinis cover more of the torso; bikinis leave the midriff more open. Coordinated pieces also allow changes in color and shape. When sold as separates, different sizes can be selected for the top and bottom.
Swim Trunks and Shorts
Children’s swim shorts range from loose trunks to close-fitting, short-legged shapes. Waist design, leg length, and lining influence comfort and dressing. Baby versions worn over a separate swim diaper need enough room for the added layer.
Ensembles de rashguard
Les ensembles anti-UV associent un haut à manches courtes ou longues à un slip ou un short. La longueur des manches et du bas détermine le degré de protection. Comme les pièces sont séparées, on peut changer de bas sans changer de haut.
Maillots de bain modestes
Les hauts et bas de maillot de bain plus longs couvrent davantage le torse et les jambes. Certains ensembles comprennent un couvre-chef, d'autres non. Les ouvertures, les proportions et la coupe doivent être adaptées à l'âge de l'enfant et lui permettre de bouger et de s'habiller facilement.
Couches de bain
Couches de bain Elles sont destinées aux enfants qui ont encore besoin d'une couche dans l'eau. Les principaux modèles de produits sont faciles à confondre :
- Couches de bain séparées : Une couche de bain réutilisable ou jetable, portée seule ou sous un maillot de bain extérieur compatible.
- Maillots de bain avec couche de bain intégrée : Un maillot de bain ou un bas de maillot de bain avec un compartiment intégré faisant office de couche de bain.
- Maillot de bain porté par-dessus une couche séparée : Un short de bain classique ou un maillot de bain avec un espace prévu pour une couche de bain en dessous. Les maillots de bain sont généralement munis de boutons ou de fermetures éclair faciles à utiliser. Le vêtement extérieur ne remplace pas la couche.
Les produits peuvent sembler similaires de l'extérieur, mais leur construction interne et leur finalité sont différentes.
Maillots de bain adaptés aux besoins spécifiques du marché
Ces besoins peuvent être satisfaits par plusieurs des types de maillots de bain mentionnés ci-dessus, notamment les maillots une pièce, les bikinis et les ensembles coordonnés.

- maillots de bain grandes tailles: L'ajustement dans la gamme de tailles prévue est aussi important que le style lui-même. La longueur du buste, la forme des bonnets, la conception des bretelles et la couvrance peuvent varier selon les modèles et les tailles.
- Maillots de bain de maternité : L'aisance au niveau du ventre, le tissu souple et les détails ajustables permettent de s'adapter aux variations de morphologie. Les maillots une pièce et les tankinis sont des choix courants, tout comme les modèles deux pièces offrant un bon maintien et une coupe adaptée.
- Maillots de bain modestes : La longueur du vêtement et la combinaison des pièces déterminent le niveau de couvrance. Choisissez un assortiment qui corresponde aux préférences de votre clientèle.
- Maillots de bain assortis pour toute la famille : Des imprimés, des couleurs ou de petits détails communs permettent de créer des harmonies entre les styles, quel que soit l'âge. Un body, un bikini et un short de bain pour bébé peuvent ainsi être assortis sans pour autant avoir la même coupe.
Comment choisir les styles pour votre collection
Commencez par réfléchir à l'usage que vous ferez du maillot de bain et aux éléments qui manquent à votre collection actuelle. Le tableau comparatif ci-dessous vous aidera à affiner votre choix.
| Ce dont vous avez besoin | Styles à envisager | Principales différences à comparer |
|---|---|---|
| Combinaisons haut-bas ou tailles séparées | Bikinis séparés, tankinis, ensembles coordonnés | Tailles disponibles pour chaque pièce, formes compatibles et vente en ensemble ou à l'unité |
| Couverture plus étendue du torse ou des hanches | Tankinis, robes de bain, bas de maillot de bain taille haute ou jupe | Longueur du haut, hauteur de la taille, longueur de la jupe et couverture du dos |
| Couverture plus étendue des bras ou des jambes | Combinaisons une pièce à manches longues, ensembles anti-UV, combinaisons de bain, ensembles pudiques | Longueur des manches et du bas, coupe et aisance de mouvement |
| Maintien et galbe de la poitrine | Hauts à armatures ou modèles avec bonnets et bandes internes | La forme du bonnet, la construction du bandeau, les bretelles et la doublure ; le nom du modèle seul ne garantit pas le maintien. |
| Baignade, surf ou simple détente sur la plage | Slips et jammers pour maillots de bain ajustés ; shorts de bain et t-shirts anti-UV pour le surf ; maillots de bain une fois détendus. | Activité prévue, ceinture, doublure, tissu et liberté de mouvement |
| Habillage et changement de couches du bébé | Maillots de bain une pièce, ensembles deux pièces, couches de bain ou maillots de bain conçus pour être portés par-dessus. | Ouvertures, fermetures, espace pour la couche et si la couche est séparée ou intégrée |
Pour les allégations de protection solaire, la longueur des manches et la surface couverte ne suffisent pas à elles seules à établir un indice UPF. Toute indication d'indice doit être étayée par des tests pertinents portant sur le matériau ou le vêtement concerné.
Choisissez d'abord les formes de base, puis ajoutez des styles qui ont une apparence ou une fonction différente. Partagé couleurs et imprimés Vous pouvez assembler les produits. Vous pouvez également réutiliser du tissu selon l'activité, mais un même matériau ne conviendra pas forcément à tous les styles.
Il faut tenir compte du travail que représente chaque conception. De nouvelles formes de bonnets, des systèmes de fermeture inédits ou des combinaisons de plusieurs pièces peuvent nécessiter un développement plus important qu'une simple variation d'un modèle existant. La charge de travail réelle dépend de la conception ; un classement fixe de la complexité serait donc trompeur.
Déterminez si la possibilité de combiner différents articles justifie l'augmentation des stocks. Les ensembles fixes sont plus simples à gérer. Les articles vendus séparément permettent de combiner tailles et styles, mais les hauts et les bas peuvent se vendre à des rythmes différents, ce qui peut entraîner des déséquilibres dans les stocks.
Une fois vos modèles présélectionnés, utilisez des images de référence pour visualiser les formes et la couvrance souhaitées. Des échantillons vous permettront ensuite d'évaluer la coupe, le maintien et le confort avant d'élargir votre choix.
