Sizing Guide
How to Measure
Wrap a soft measuring tape around the smallest part of your waist — usually slightly above your belly button.
Keep the tape snug but not tight.
Stand relaxed and breathe normally while measuring.
Once you have your waist measurement, find your size below.

Important

If you are between sizes, choose the size that corresponds to your real waist measurement — do not size down.

Care Guide
Care Instructions
To preserve the quality of your garment, wash cold on a gentle cycle and always use a laundry bag to prevent snagging. For best results, air dry your pieces naturally and strictly avoid the use of bleach or high heat, which can damage the fibers over time.
