1. Measure Your Underbust
Stand with your arms resting by your side and ideally get someone else to measure around your body, directly below the bust. Make sure the tape is right under your breasts, is straight all the way around and is as tight as possible.
This is how the underband of the bra will fit, so the tape should be tight, but not uncomfortable. It’s best to do this measurement while you’re not wearing a bra, or you can do it wearing one, just be careful not to sit the tape over your bra or underwire.
2. Measure Your Overbust
Measure around the fullest part of your bust (usually over the nipple). This is best done while you’re wearing a bra. Hold the tape gently so it is resting lightly on your body. Make sure the tape measure is straight across your back, and sits parallel to the floor.
3. Calculate Your Cup Size
Subtract your band size from your bust measurement and refer to chart. Example: 37 inches (bust) – 34 inches (band) = 3 inches. That’s a 34C.
