Waist Trainer Shapers for Women & Men Slimming Fit

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.

Size chart

Some styles run differently, so always check the size chart on the product page too.

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.

Sizing Tip

Measure your natural waist (the narrowest part of your torso) with the tape snug but not tight, then check the size chart. Between sizes? Choose the larger one. It should feel like a firm hug, and you should always be able to breathe deeply.

Wear It Comfortably

Start with a couple of hours a day and build up gradually. Loosen or remove it if you feel pinching, numbness or shortness of breath, and never over-tighten. Shapewear smooths your look while you wear it; it doesn't permanently change your body. If you are pregnant, postpartum or recovering from surgery, follow your doctor's guidance before wearing compression.
