We've done our best to take out the guesswork and make finding your cup-band bra size simple. Push-ups and padding can skew things, so pull on a shelf bra camisole or your best fitting everyday bra.
Step 1: Measure around your chest, just under the arms and above the bust. Make sure that the tape measure is taut and is straight across your back, but not tight, or that could result in a squeeze later. Breathe out, relax your shoulders. We'll get through this together. If the measurement is an odd number or a half size, round it up to the next even number (for example, 33 will actually be 34). This number is known as your band size. Unsure you've got it right? Take a seat - our chests expand some when seated.
Step 2: Now it's time to measure your cup size. Measure around the fullest point of your bust. This could be at the nipple, but everyone's body is different. This will be one of two measurements that you need to determine your cup size.
Step 3: For the final measurement, measure just under the bust around your ribcage.
Got the measurements? Good. It's time to calculate your bra size.
