Should I Size Down in Shapewear for Better Results?

Thinking about sizing down in shapewear or waist trainers to speed up results? You're not alone. It’s one of the most common questions shapewear shoppers ask. But here’s the truth: sizing down can actually backfire. The key to comfort, contour, and long-term success is choosing the right fit based on your natural waist measurement, not your clothing size.

Let’s bust the myth and help you find your perfect fit.

Embrace the Measuring Tape

Top Tips for Perfect-Fitting Shapewear & Waist Trainers

1. Embrace the Measuring Tape

Forget dress sizes, your natural waist measurement in inches is the key to a perfect fit. Our high-compression shapewear is designed to reduce your waist by 2-3 inches, so choose your actual waist size for a snug, comfortable fit. All our shapewear styles are sized by waist measurement in inches, except for our men’s shapewear slimming vests, which is sized by chest measurement. Please refer to the product-specific size chart for accurate fit.

> How to measure your waist: Wrap a tape around the narrowest part of your torso (where you'd tie a belt), breathing naturally.

How to measure your chest: Wrap a measuring tape around the fullest part of your chest, keeping it level across your back and front. Stand relaxed, breathe naturally, and ensure the tape sits snugly without digging in.
