Choosing by swimsuit type
One-piece swimsuit
Compare your bust, waist, and hip measurements. Use the measurement corresponding to the largest size.
Bikini top
Choose based on your underbust and bust measurements, then check the cup depth indicated on the product.
Bikini bottom
Base this mainly on your hip measurement. The edge should stay in place without compressing.
Tankini
Choose based on your bust and hips. The lower part should drape naturally without riding up.
Multi-fit cup style
Multi-fit styles are designed to accommodate several cup depths thanks to their stretchy material and adjustable features.
Shapewear swimsuit
The shaping lining should smooth and support the silhouette while allowing you to breathe and move comfortably.
Beachwear
Use your bust and hip measurements primarily, then choose based on the desired level of ease.
UV protection top
Choose based on your bust measurement. For a looser fit, choose the next size up.
Torso length
Short torso
Opt for styles with adjustable straps, halter styles, or two-piece sets to customize the fit.
Long torso
Choose a style with adjustable straps, a halter style, or a tankini. A larger size may also offer more length.
How to recognize a good fit
At the bust
The bust should be fully enclosed, without overflowing or leaving empty space in the cups.
Under the bust
The band should remain stable and horizontal without riding up or compressing.
At the waist
The material should smooth the silhouette without hindering breathing or movement.
At the hips
The fabric should stay in place without cutting into the hips or creating tension folds.
Cup depth, torso length, and support level can affect the fit. Our team can help you choose the Sea Level style that suits you best.
