Fit Guide

 

Fit & Feel

Our fabrics are soft and flexible, designed to move with your body rather than restrict it. 

Most styles fit true to size. 

 

Between Sizes

If you are between sizes, we recommend sizing up for comfort. 

 

Briefs 

  • True to size for a secure fit
  • Size up for a more relaxed feel

 

Thongs

  • Designed for a smooth, minimal finish
  • True to size

 

Fabrics 

  • Stretch fabrics adapt to your shape
  • Lace styles may feel slightly more flexible
