Your Bra Lab Size Is
Here’s How it Works
The Bra Lab sizing system is simple: your cup and back band are sized separately. This allows you to create a bra that fits your unique proportions.
Option 1: Convert Your Current Bra Size Enter your current band and cup size into our size converter. We’ll show you your Bra Lab cup size and back-band size.
Option 2: Measure Yourself and Email Us Take these two snug measurements: Underbust: Measure directly under your bust, keeping the tape level around your body. Full bust: Measure around the fullest part of your bust. For the most accurate results, wear an unpadded bra, keep the measuring tape straight, and measure snugly without pulling it too tight. Email both measurements to shop@thebralab.com, and we’ll personally help you find your correct Bra Lab cup and back-band sizes.
With our new system, combining these two separate measurements gives us the ability to offer a wider range of sizes than any other bra. Together they give you a size specific to your body. Since our bras are made with a two-piece modular design and not a prefabricated unit, our cups and bands fit YOU uniquely. Ready to build your perfect bra? Start Here

MelissaI love these bras! I’m too endowed to go without a bra, so these allow me to wear the backless or cut out shirts that are really popular, while still getting support.
SabrinaOMG I LOVE this bra and how customizable it is. Instead of needing to get a bunch of different bras in different colors you can just get different straps and backs!
AmberCustomer for life! I just got mine in the mail and oh my gosh!! I'm in love! Time to buy a ton of backless shirts that I've never been able to wear before. The fit is amazing.
JacquelineI'm so happy with my set! It's a struggle finding bras that have big cups and small bands and I LOVE the idea!
