Size confidence
Swimsuit size chart (cm)
Standard conversion used by most swimwear brands. If you are between sizes, go up for one-pieces and down for high-compression bikinis.

How to read the chart
Find the row where at least two of bust, waist and hip land. If the third is two rows away, you are between sizes. For a one-piece, take the larger size; for a bikini top, match the bust band first.
One-piece versus bikini
A one-piece has fixed seams, so an undersized suit pulls at the shoulder and waist. A bikini has two independent fits: match the bust and underbust for the top, and the hip for the bottom.
Fabric matters
Less than 10% elastane runs tight; 10-18% is standard; over 18% is forgiving but can thin when wet. Check composition on the product page before you order.
Preview before you buy
A size chart answers the number. A visual preview answers the cut: where the neckline lands, how high the leg sits, and whether the print reads at full-body scale.
