Sizing Chart
Made for the female body in motion.
Endurance wear designed around female athletes — drafted from the way a woman's body moves through swim, bike, and run, finished in original hand-drawn prints by founder Liz Tremain. Here's how to find your size.
Three measurements. One soft tape.
Wear thin clothing or measure over a sports bra and shorts. Pull the tape snug — not tight. Measure twice if a number feels off.
-
01 — Bust
Around the fullest part of your chest.
Tape level all the way around. Arms relaxed at your sides, not lifted.
-
02 — Waist
Your natural waist — the narrowest point.
Roughly an inch above your belly button. Stand normally; don't suck in.
-
03 — Hip
The fullest part of your hips and seat.
Stand with feet together. Tape parallel to the floor, usually 7–9 inches below your waist.
