how to measure
stand in front of a larger mirror wearing a non-padded bra. it may take some time to get used to, that's to be expected.
band size
wrap a soft measuring tape around the back at the band level, under each arm and around the front. this is a little tricky, so asking someone you trust may help. measure just above the chest, right where the straps meet the top of the cup. this is your band size.
chest
keeping the tape around the body at the band level, measure at the fullest part of the chest. make sure the tape isn't too tight by taking a deep breath in and out to allow the tape to slide to its most comfy, yet snug position. this is your chest size.

fit tips

if one of your measurements is on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. consider your height first when finding your size, then your body measurements.

if your measurements for hip and waist correspond to two different suggested sizes, order the one indicated by your hip measurement.
