Hip Size Guide

Our underwear and shorts designed to sit low on the hips. So its only right to measure your hips instead of your waist. If this is your first time buying SUPAWEAR we recommend going up a size.

Check out the video so you can choose the right SUPAWEAR size.

As a guide

Zara, Abercrombie, Addicted(Spain) CK will be the same sizing match to our brand. If you wear Toots(Japan) our sizing is bigger so you will need to go down a size. If you wear Aussiebum our sizing is smaller so you need to go up a size.
