Size guide

Find the perfect size to fully enjoy the support and comfort of your swimwear.

How to take your measurements

1

Measure your underbust

Place the tape measure directly under your bust. Keep it horizontal and snug against your body, without pulling it too tight.

2

Measure your bust

Place the tape measure around the fullest part of your bust, without compressing your breasts.

3

Measure your waist

Place the tape measure around the narrowest part of your natural waist, without sucking in your stomach.

4

Measure your hips

Measure the fullest part of your hips and buttocks, keeping the tape measure horizontal.

Cyell Tip: Take your measurements while wearing a comfortable, non-padded bra. If you are between two sizes for a one-piece swimsuit, choose the larger one.

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.
