ThirdLove is for shoppers who consistently fall between standard sizes and want a guided online fitting experience. The half-cup sizing (32B½, 34DD½) catches the gap whole-cup brands miss. If you've struggled to commit to a size because you're always between the choices, ThirdLove's quiz plus half-cups is built for exactly that situation.
Price positioning. Premium — typical wired styles $58-72, t-shirt molded cups $65-78. Sits in the same range as Wacoal. The premium pays for half-cup sizing (which requires more SKUs to inventory), memory-foam cup construction, and the online fit-finder infrastructure. If you don't fall between sizes, ThirdLove's premium isn't buying the value the brand is built around.
Half-cup sizing available; cups run slightly generous.
