The 1-piece swimming costume: an elegant, timeless ally


The women's 1-piece swimming costume has become a summer wardrobe essential. Elegant, comfortable and on-trend, they are just as appealing for the beach as they are for the pool, thanks to their flattering cut and excellent support. Long considered a classic, the 1-piece swimming costume is now being reinvented with modern designs, comfortable fabrics and feminine details: bare backs, plunging necklines, asymmetric cuts, sheathing effects and sculpting models.
In our 1-piece swimwear outlet collection, you 'll find top brands at clearance prices, so you can enjoy quality without paying full price. Whether you're looking for a cheap women's swimming costume for holidays, a figure-enhancing model or a sports swimming costume for swimming, our selection has something for everyone.
Discover 1-piece swimwear by O'Neill, Nike, Roxy, Sun Project or Haute Pression at reduced prices thanks to our clearance policy.

Which 1-piece swimming costume is right for you?


For an A shape


A-line silhouettes, with hips that are larger than the shoulders, can opt for 1-piece swimming costumes with details on the upper body: worked necklines, prints, ruffles or original straps. More sober colours on the bottom naturally balance out the silhouette.

For an H-shaped silhouette


Women with an H-shaped silhouette can opt for one-piece swimming costumes that are belted, draped or have cut-outs at the waist to create more curves. Asymmetrical or cutaway styles also add a more feminine touch.

For larger breasts


Generous breasts need good support to combine comfort and elegance. One-piece swimming costumes with underwiring, integrated cups or wide straps are ideal for supporting the bust while enhancing the silhouette. Unlike the two previous morphotypes, avoid draping and details on the upper part of the body that could make the bust feel heavy.

To elongate the figure


Low-cut models, plain or with vertical cut-outs, help to visually elongate the silhouette. Black or dark 1-piece swimming costumes are still essential for an elegant, slightly slimming effect.

Find the swimming costume that will enhance your figure in our collection of cheap women's 1-piece swimming costumes. If you prefer 2-piece swimwear, check out our low-priced bikini category.

FAQ One-piece swimming costumes


Which 1-piece swimming costume will slim your figure?

Black, plain or sheer 1-piece swimming costumes are the most effective for visually slimming the figure.

Is the 1-piece swimming costume trendy?

Yes, the 1-piece swimming costume is more fashionable than ever. The current collections offer modern models with asymmetrical cuts, elegant halter tops, trendy prints and feminine details that make them a real fashion statement.

Which swimming costume to choose during pregnancy?

During pregnancy, choose a comfortable maternity swimming costume with stretch fabrics, wide straps and good bust support. Sheer 1-piece models or tankinis are ideal for supporting your growing tummy while remaining comfortable on the beach or in the pool. Also check out our special pregnancy swimwear collection, always at low prices.

How do I choose my size?

To choose the right 1-piece swimming costume size, it's important to take into account your bust size, your hip size and your desired level of support. If you're hesitating between two sizes, generally opt for the larger one for greater comfort, especially on shaping or sculpting models.
