Did you know that 80% of women are wearing the wrong size bra? Finding the perfect bra for your shape, size and style starts with knowing your correct size. Use our bra-size-calculator to determine your band and cup size. To measure yourself for a bra at home, follow these quick and easy DIY Bra Sizing steps.

Once you have the right cup size and band size as a base, use our Bra Fit Checklist to ensure you buy a bra that supports and shapes you perfectly. Need more information? Chat with our Lingerie Experts or explore HerRoom's bra fit resources.

The best bras for support are seamed cup bras. Also known as multi-part cup bras or cut and sew bras, the seam cupped bra’s design is made up of two or more fabric pieces sewn together. The seaming technology and the materials used work together to provide the perfect amount of support and shaping capabilities, making them the best bras for heavier breasts.

When you shop online, you have a variety of bras to choose from, as well as convenience and privacy. The average bra comes in 24 sizes – so a store that carries three colors of a bra will need 72 bras. That’s a lot of inventory. In contrast, online bra stores like HerRoom can provide a wide range of sizes (from cups AA to P and band sizes from 28 to 56) and styles that wouldn't normally be available in a store. 

Online shopping for lingerie can be easy, enjoyable and educational. Check out the helpful tools in our Lingerie Expert Center – all created for at-home shoppers – to help you choose the best fit, style and size for you. Plus, you can shop confidently knowing that you can return your bra in new condition within 30 days for a refund. See the return and exchange details.
