Our swimsuits are stretchy (up to 10-15cm). The size you choose will be dependent on how you prefer to wear your swimsuit. Our swimsuits are seamless, they are designed to not dig in tight around the legs / hips. For a snug fit (one that isn't loose / has excess creases of fabric) we recommend choosing the size that is closest to 10/15cm below your body measurement. eg. if your waist is 115cm around, choose the pair that is 100cm around. The swimsuit will conform to your body over time as you wear it. The tables below are the actual garment measurements.
