TomboyX

TomboyX makes inclusive underwear designed for all genders and body types in sizes XS to 6X. The brand uses sustainable materials and offers styles ranging from boxer briefs to bikinis, with period-specific lines that start around $22 per piece or $66–$97 for three-packs. It suits anyone seeking comfortable, gender-neutral everyday wear or period protection with a modern fit.

Who TomboyX Is and What They Stand For

TomboyX was founded in 2013 by queer and women-identified entrepreneurs who saw a gap in the market for inclusive, high-performance underwear. The brand set out to create pieces that worked beyond conventional expectations, focusing on quality, fit, and function for people of all gender expressions and body sizes. In 2019, TomboyX expanded to develop gender-affirming underwear and safer alternatives to binders, recognizing the needs of trans customers. According to their origin story, the founders spent considerable effort perfecting core details like the waistband—seeking a silky-soft feel with the right thickness to prevent rolling and ensure durability. They partnered with a woman-owned factory for production and fit-tested designs across all sizes before launch. Today, the brand continues to evolve its color and style options based on direct customer feedback, maintaining its commitment to inclusivity and sustainability throughout its operations.
