Waist Trainer Body Shaper 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.

How to Choose Your Size

Measure your natural waist (the narrowest part of your torso) without pulling the tape tight, then compare with the size chart. If you're between sizes, choose the larger size. A waist trainer should feel snug and supportive, never painful, and you should always be able to breathe deeply.

Tips for Wearing Your Waist Trainer

• Start with 1 to 2 hours a day and build up gradually.
• Wear a thin cotton layer underneath for extra comfort.
• Loosen or remove it if you feel pinching, numbness or shortness of breath.
• Drink plenty of water, especially during workouts.

A waist trainer shapes your look while you wear it; it doesn't replace exercise or permanently change your body. If you're pregnant, postpartum or recovering from surgery, check with your doctor before use.
