📏 How to measure
- Waist: wrap a soft tape around your natural waist, over a thin shirt. Keep it snug but not tight.
- Pants waistband: lay the pants flat, measure across the top of the waistband and double it.
- Hips: measure around the widest part of your hips and seat.
- Height: stand straight without shoes against a wall.
- Between two sizes? Pick the larger size for slim fits and the smaller size for loose fits.
