Choosing by style
Bandeau top
The back band must be firm enough to keep the top securely in place, even when straps are removed.
Full-coverage top
Choose a cup that fully encloses the bust without spilling over. This cut is particularly suitable for deeper cup sizes.
Plunging top
Check that the bust stays centered and the edge of the cup does not cut into your curves.
Triangle top
Adjustable ties make it easy to customize the fit. Use your bust measurement as your main reference.
Tankini
Choose the top according to your bra size and the bottom according to your hip measurement.
One-piece swimsuit
Use the measurement corresponding to the fullest part of your figure and take torso length into account.
High-waisted bottom
Compare your waist and hip measurements. Choose the size corresponding to the largest measurement.
Regular or high-leg bottom
Use your hip measurement primarily, then choose the desired level of coverage.
