For too long, the bra industry was stuck in outdated ideas, forcing women to choose between feeling sexy or comfortable. So in 2013, Heidi Zak and Ra’el Cohen created Thirdlove–a third, better option designed to help women look and feel their best.
Prioritizing real-world fit over outdated standards, Thirdlove disrupted the industry by inventing half-cup sizes and the Fitting Room® quiz. The result was a more precise fit that offered comfort without sacrificing style. Building on that approach, Thirdlove is expanding its retail footprint nationwide, creating customer-first stores where personalized fittings, expert support, and a comfortable shopping experience come together.
Our culture is collaborative, fast-paced, customer-focused, and welcoming. If that sounds like an environment where you would thrive, we encourage you to apply.
