Swim Costumes

A great swimsuit holds its shape through a season of use, provides adequate support, and flatters through cut rather than coverage. Look for chlorine-resistant fabric and proper lining.

01
Chlorine-resistant fabric lasts significantly longer than standard lycra
02
Adjustable straps and underwire provide better support for different needs
03
A one-piece swimsuit in a solid colour is the most versatile option

Sculpture Shaping Swimsuit

Speedo makes the most technically accomplished swimsuit at this price — chlorine-resistant fabric that holds its shape and colour through a full season of daily swimming, a shaping panel that provides gentle support without compression, and a cut that's designed around actual swimming rather than poolside posing. The choice of serious swimmers and the best value in the category.

Belted One Piece

Heidi Klein makes the swimwear that fashion-conscious women actually buy for holidays — a belted one-piece silhouette that creates a waist, Italian fabric that maintains its shape through a full two-week holiday, and colours that photograph beautifully in natural light. The fit is proper across the bust rather than leaving you adjusting constantly. The swimsuit for people who take their swimwear as seriously as the rest of their wardrobe.

Ace One Piece

Eres is the French swimwear brand that women who care about swimwear eventually arrive at. The Ace uses their proprietary Smartissue fabric — more resistant to chlorine, sunscreen, and seawater than any other material in the category — and the construction involves 26 pieces per suit, each cut by hand. The fit is precise in a way that requires trying other swimsuits to fully appreciate. The last swimsuit most women ever need to buy.
