I wasn't sure on sizing. I was gonna go a medium just to be safe because I was nervous on sizing. After messaging with them thru email and comparing to other belts I have. They all matched up to an xs. While I was talking to them I figured I'd ask about and exchange if needed since I was already talking to them. Simple yes nothing more. Fast forward I can't even get the belt around me and I'm pretty small typical where size 25 jeans. Ask about going thru with the exchange to be told it will be an extra 30 dollars plus shipping covered by me back to them. Honestly I'm highly disappointed and not recommend them
