HOW TO MEASURE
Bra: Using measuring tape, measure under your bust ensuring the tape is snug. Take that measurement, round up to the nearest whole number. If the number is even add 4, if odd add 5.
Example: Under bust is 31 1/2" round to 32" add 4, so your bust is 36.
Next measure around your BUST, this is usually nipple level around the body. Once you have that measurement subtract the under bust from the bust, with the reminder follow the cart below to find your cup size.
