TomboyX

TomboyX is an underwear brand that started in 2013 to address a gap in the market for underwear that anybody could feel comfortable in, inclusive of all sizes and gender expressions. The brand describes itself as queer- and women-founded and says it began by focusing on the waistband and eco-friendly fabrics, fit-testing on people of all sizes. Its first run of boxer briefs — the 4.5" Trunk and the 6" Button Fly — was made with a woman-owned factory and sold out in a two-week presale. TomboyX later added boy shorts, briefs, and soft bras, and in 2019 developed new product lines to serve trans folks looking for gender affirming underwear and safer alternatives to binders. The brand markets its products as "Underclothes to feel good in your overclothes" and "Gender affirming tops and bottoms."

TomboyX started in 2013 because the founders recognized a gap in the market for people like them, asking "How hard can it be to make good underwear?" — meaning underwear that anybody could feel comfortable in, inclusive of all sizes and gender expressions. The brand describes itself as queer- and women-founded and says that over 10 years ago it began working on better underwear options for people who were failed by the status quo, aiming for sustainable underwear focused on quality, fit and function. The first product priority was the waistband; after achieving a silky-soft feel, the right thickness to prevent rolling, and long-lasting quality, the brand selected eco-friendly fabrics and fit-tested on people of all sizes. Its first run of boxer briefs — the 4.5" Trunk and the 6" Button Fly — was produced with a woman-owned factory, and the presale sold out in just two weeks, which the brand calls its hero product moment. TomboyX then added boy shorts, briefs, and soft bras. In 2019, it developed new product lines to serve trans folks looking for gender affirming underwear and safer alternatives to binders. The brand states it continues to work on new color and style options based on customer feedback and credits its community — a diverse circle of LGBTQ+ folks, athletes, people outside the confined size spectrum, and those who like quality, all-day comfort — for its progress.
