Our nylon straps are measured by the tightest length unstretched and the longest length stretched.
XS: 00-4 S: 4-8 M: 8-12 L:12-18
Each piece can be used differently on the body so I would suggest to fit it to your most desired look.
If you have any questions please feel free to contact me. Custom strap lengths can be created upon request.
Chart coming soon.
