How to measure ?

Bust: Wrap the measuring tape around the fullest part of your bust. To get the most accurate measurement, get a flexible plastic measuring tape and bring it around your torso to the fullest part of your breasts. Position the tape directly over your nipples and relax your arms at your sides. If possible, get someone to help you take the measurement so you’re able to keep your arms down.

Body width: Length between the stitches below the armpits.
