ThirdLove is a direct to consumer bras brand that invented sizes for bras in half-cup sizes, to better serve the 50% of women who don’t measure exactly with a traditional cup size.

The ThirdLove shopping experience begins with a helpful “find your fit” tool, and then offers the ability to filter all products by your size (via their Shop by Size page).

A further industry-changing innovation is their “try before you buy” return policy, which allows for gently worn bras to be returned and exchanged. Returned bras are donated to local charities in San Francisco, where the brand is headquartered.

In addition to bras, this popular brand also sells underwear, t-shirts, sleepwear, and bodysuits!
