Here’s Why it Works
The Bra Lab has a new and improved, simplified sizing system that has revolutionized bra sizing. It is important while measuring that you place the measuring tape across the fullest part of your bust and directly under your bust to get an accurate read. MEASURE SNUGLY!
Your back band size relates to your measurement and comes in sizes XS-XL, please use our size converter to find the correct conversion.
Your cup size relates to your measurements or you can enter your current bra size to get your TBL conversion. Traditional bra sizes change depending on the relationship between your band and bust, so a 36D has a larger cup and band than a 32D, leaving us all really confused.
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

Start a chatMelissaI 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!
