How to measure your hips

Stand on a level surface, feet together without shoes.
Measure around the fullest part of your hips and bottom - this is usually 7-9" below your natural waistline.
Keep the tape measure parallel to the floor, and don't pull too tight.

Self-love in shades of merlot, plum and trans pink, priced for everyday. We took a classic and made it into a TomboyX icon, the first truly gender-neutral boxer brief. These classically-styled Tomboy trunks pair quality cotton with just the right amount of stretch for a smooth, body-hugging fit.

  • Includes one pair each of Merlot, Plum, and Trans Pink
  • Fit-tested on all body types, sizes XS-4X
  • Signature stay-put silky soft TomboyX waistband
  • 95% OEKO-TEX Certified cotton, 5% spandex
  • Smooth, durable flatlock seams won’t irritate or chafe
  • Mid rise fit, 4.5” inseam
  • Machine wash cold, tumble dry low

    Pairs in our Multi Packs have fewer seams than pairs you may buy individually. The fit is smooth and slightly more snug, but the sizing — and the buttery-soft waistband — are the same.
