How to measure
Use a soft measuring tape and measure over light clothing. Keep the tape snug but not tight.
- Bust: measure around the fullest part of your bust, keeping the tape level under your arms and across your back.
- Waist: measure around your natural waistline — the narrowest part of your torso, usually just above the belly button.
- Hips: stand with your feet together and measure around the fullest part of your hips.
- Inseam (pants): measure from the top of your inner thigh down to where you want the hem to fall.
Fit tips
- If you're between sizes, choose the larger size for a more relaxed fit, or the smaller size for a closer fit.
- When a product runs small, its product page will say so — follow that recommendation.
- Oversized styles are designed to be roomy; check the garment measurements on the product page to find your preferred fit.
