How to measure your size (women)
Use a flexible measuring tape and measure directly on your body. Don't pull the tape too tight—it should fit snugly, but not constrict.
The four most important sizes for women are:
Chest circumference
Measure around the fullest part of the bust, horizontally around the body.
Waist circumference
Measure the narrowest part of the waist, usually just above the navel.
Hip circumference
Measure around the widest point of your hips and buttocks. The hip measurement is the most important when choosing your competition swimsuit, as the suit must be pulled on over your hips. If the suit is too small around the hips, you simply won't be able to put it on properly.
Bodyloop (torso)
Starting at the top of one shoulder, run the measuring tape between your legs and back up to the starting point. This gives you the total length of the suit and determines whether it feels too short or too long.
