Swimwear sizing makes no sense. Measure yourself anyway.

The measurements are easy: bust, waist, hips. The hard part is that every brand interprets those numbers differently, so don’t expect a perfect fit on the first try.

Use a soft measuring tape (not a hard ruler or string and ruler — you want it to curve). Stand straight, wear the underwear you’d wear under swimwear, and measure: bust at the fullest part, waist at the narrowest point (usually just above your belly button), hips at the widest point (around your butt). Write those numbers down in inches and centimeters, because some brands use one, some the other.

Now ignore the generic size charts on Amazon
