If you aren't sure of your bra size and want to measure first, here's how...It's slightly more complex, but still easy. You take a tape measure and measure around your bust, then band. This gives you two numbers. You can send us an email with these two numbers shop@thebralab.com or use the chat box.
If you want to do it yourself, the cup size can be calculated using the difference between bust size and band size.
