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.

Bold, basic, black: the perfect tone for gothy vibes or just keeping it simple. The last thing you needed to have complicated when you're on the move is the call of nature. These boy shorts start with the same lightweight, breathable and quick-drying jacquard jersey knit as our Traveler underwear and add to that a front-to-back crotch opening that accommodates an STP (stand to pee) device. Ensure a little extra convenience and confidence when it's time to go on the go.
