Plus Size Waist Trainer for Women – Full Coverage Support

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.

Our Plus Size Waist Trainer is made for curvy bodies that want firm, comfortable shaping. Breathable, high-quality materials give a defined waist and a smoother midsection while you wear it, without feeling restrictive.

How It Shapes

• Firm compression around the waist and abdomen for a more defined, balanced silhouette
• Structured design that smooths the tummy area and supports upright posture while worn
• Low-profile fit that sits discreetly under dresses, tops, workout outfits and everyday clothes

Comfort Features

• Adjustable closure so you can set the fit to your body and comfort level
• Flexible fabric that moves with you when you sit, walk and bend
• Breathable materials that help reduce heat buildup during longer wear

When to Wear It

Daily wear, light workouts, work days and special occasions — anytime you want extra midsection support and a confident, sculpted look.

Sizing Tip

Measure your natural waist (the narrowest part, usually just above the belly button) and choose your size from the size chart. If you are between sizes, size up for comfort — you should be able to breathe deeply and sit without pinching.

Shapewear smooths and supports while it's worn; it does not permanently change your body shape. If you're pregnant, recovering from surgery or have a medical condition, follow your doctor's guidance, and never over-tighten your waist trainer.
