Shapewear & Faja Size Guide | How to Measure & Size Chart

The right size is what makes shapewear work. Too small and it rolls, digs in and feels painful; too big and it won't smooth. Use this guide to find your size for Cups Brazil fajas, bodysuits, shaper panties and waist trainers.

How to measure

  1. Waist: measure around your natural waist, the narrowest part of your torso, usually just above your belly button. Keep the tape snug but not tight.
  2. Hips: stand with feet together and measure around the fullest part of your hips and seat.
  3. Measure over bare skin or thin underwear, and breathe normally.

Sizing tips

  • Between sizes? Choose the larger one. Shapewear should feel snug, never painful.
  • Waist and hips in different sizes? For waist trainers, go by your waist. For panties, shorts and bodysuits, go by your hips. For full-body fajas, go by the larger measurement.
  • Waist trainers: start on the loosest hook row and build up wear time gradually.
  • Post-surgery fajas: follow your surgeon's sizing and compression guidance.
  • Fit check: you should be able to breathe deeply, sit for 15 minutes and move freely.
