Fit tip: Forever 21 fit varies by style and fabric, so compare your measurements with each chart and size up in non-stretch fabrics if you're between sizes.
How to measure
- Chest / bust: around the fullest part, keeping the tape level.
- Waist: around the narrowest part, usually at the belly button.
- Hips: around the widest part of your seat.
- Foot length: stand on paper, mark from heel to longest toe, then measure the line.
Use a soft tape over light clothing, snug but not tight.
