RARP-ID Fitness Size Guide

All RARP-ID activewear is made to order by Printful. Use the measurements below to find your perfect fit. Sizes are based on body measurements — measure yourself and match to the chart rather than comparing to other brands.

How to Measure

  • Chest/Bust: Measure around the fullest part of your chest, keeping the tape parallel to the floor
  • Waist: Measure around the narrowest part of your waist
  • Hips: Measure around the fullest part of your hips

If you fall between two sizes, we recommend sizing up for a more comfortable fit.

Sizing Notes

  • All RARP-ID activewear is made to order — each item is cut and sewn individually, so measurements may vary by up to 1 inch (2.5 cm)
  • Compression fabrics (leggings, yoga shorts, sports bras) are designed to fit snugly — this is intentional
  • If you are between sizes, we generally recommend sizing up
