How to measure yourself
For the most accurate size prediction, measure yourself with a soft tape measure. Here's how:
| Measurement | How to measure | Why it matters |
|---|---|---|
| Bust / Chest | Wrap tape around the fullest part of your chest, parallel to the floor | Determines top and dress size |
| Waist | Measure your natural waist — the narrowest point, usually above the belly button | Key for jeans and trousers |
| Hips | Measure around the widest part of your hips and bottom | Critical for dresses and skirts |
| Inseam | From crotch to floor along the inside of your leg | Determines trouser length |
| Foot length | Trace foot on paper, measure heel to longest toe | For accurate shoe sizing |
