ThirdLove was founded in 2013 by former Google executive Heidi Zak and her husband, David Spector, out of frustration with the traditional bra shopping experience. The San Francisco-based brand disrupted the lingerie industry by pioneering a data-centric approach to fit, famously introducing half-cup sizes to cater to women who fell between standard measurements. At its core, ThirdLove champions inclusivity and body positivity, a message it reinforces through its diverse marketing campaigns and expansive size range. The brand's signature product is the 24/7® Classic T-Shirt Bra, which was developed using measurements and feedback from millions of women via an online Fit Finder® quiz.
