How to Measure Your Body for Cosplay Costumes

Sep 21, 2026

A skin-tight suit lives or dies by its measurements. Before you order, grab a soft tape and follow these steps based on the ISO 8559-1 method.

Bust: measure around the fullest part, keeping the tape parallel to the floor. Waist: measure at your natural waistline, the narrowest point. Hips: stand with feet together and measure the widest part. For bodysuits, also note your height, shoulder width and inseam.

Ask a friend to help, stand relaxed, and never pull the tape tight. When in doubt, size up: our team double-checks every order and will email you if something looks off. Get your numbers right once and every suit from coshalloween fits like it was painted on.
