Since 2014, our sister-founded small business has been rethinking the bra around you—and your wardrobe. Our innovative mix-and-match system lets you pair cups, bands, and straps separately, so you can fine-tune your fit for your unique proportions instead of settling for a standard bra size. With 80+ size combinations and interchangeable styles, you get the support you need for everything from hard-to-fit proportions to tricky necklines, low backs, and special outfits. Made by sisters, designed for real women, and created to make getting dressed easier.

Find My Size & Bra

1. Find Your TBL Size

Simply enter your usual bra size—such as 34D—into our size converter to find your corresponding TBL cup number and band size.

2. Choose Your Cup

Select your recommended cup size, then choose the cup style and color that best suit your fit preferences and wardrobe.

3. Add Your Band and Straps

Choose the recommended band size to complete your bra. Add optional shoulder straps for more styling possibilities, including strapless, halter, crisscross, and traditional configurations.

Because the cups, bands, and straps are interchangeable, you can change the fit, color, or styling without purchasing an entirely new bra.

MEET GINA & JENNIFER:

The sisters behind the bra lab

We’re sisters, innovators, and women who believe getting dressed should feel easier—not more complicated.

As the founders of The Bra Lab, we set out to rethink the products women rely on every day. Each of our designs begins with a real wardrobe challenge and one simple question: How can we make this work better?

By combining innovative fabrics, thoughtful design, and smart technology, we create intuitive pieces that adapt to you. Our products are multiuse, multiway, and designed to work together—giving you more comfort, more flexibility, and more possibilities for every outfit.

Created by women, for women—and made to move through life your way.

Rule Breaking by Design

PATENTED, MODERN, INTERCHANGEABLE SYSTEM

Bras needed a breakthrough, so we took them apart and started over.

Our innovative dual side-clasp design reimagines the traditional bra, creating a clean, smooth look that works beautifully under more outfits. It also allows us to offer better support and an expanded range of up to 80 sizes.

Building your bra is simple: use the size converter on any product page, choose your cup style and color, then add a back band and optional shoulder straps. Every piece works together, so you can interchange cups, bands, and straps to create the fit, function, and look your wardrobe needs.

One bra system. Endless possibilities. No outdated rules.

Pair the cup, back band, and straps that give you the support, coverage, and look your neckline needs.
