ThirdLove is an American lingerie company founded by Heidi Zak and her husband, David Spector, in 2013. The brand is known for marketing body positivity and offering size-inclusive bras and half-cup sizes. ThirdLove is also known for its online FitFinder quiz, which helps users determine their best fit bra and style.

For ThirdLove, the company, the product, and the name, started with the idea that for too long, women were forced to choose between two options when it came to bras: over-the-top sexy, and unflattering modesty – neither one looked great. And so, she created a third option.

People took photos of themselves using ThirdLove's proprietary app; computer vision technology then processed the images, and suggested a personalized fit.

ThirdLove is an American lingerie company founded by Heidi Zak and Ra'el Cohen, two women in San Francisco, CA. As women who wear bras and with friends who wear bras, they set out to make a better fitting & more comfortable bra.

The verdict: Are ThirdLove bras worth it? After years of testing bras from ThirdLove in the Textiles Lab and with our consumer testers, we feel that the brand's bras are worth it, especially the 24/7 Classic T-Shirt Bra, which is designed for everyday wear.
