Vest Posture Corrector for Better Daily Posture

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.

This lightweight vest posture corrector gives gentle support to your shoulders and upper back, acting as a comfortable reminder to sit and stand tall during long days at a desk, on your phone or studying. It's slim enough to wear under or over clothing at home, at work or at school.

How It Works

The vest gently guides your shoulders back into a more natural position. Instead of forcing a rigid posture, it helps you notice when you start to slouch, so you can build better posture habits during everyday tasks. Adjustable straps and a flexible structure let you set the fit so it feels supportive without being restrictive.

• Lightweight, breathable vest design
• Adjustable straps for a personalized fit

Sizing Tip

Measure around your chest just under the arms and choose your size from that number. If you're between sizes, size up for comfort. The vest should feel supportive, never tight enough to restrict breathing or pinch under the arms.

This vest is a comfort and posture-awareness accessory, not a medical device. If you have back, neck or shoulder pain or an existing condition, follow your doctor's guidance before use, and never over-tighten the straps.
