8 Best Tummy-Control Underwear, Tested by Glamour Editors

To find the best tummy-control underwear, we researched top-rated styles from major retailers and analyzed user reviews to narrow down more than 15 options. Over six weeks, Glamour editors and contributors tested each pair for material quality, fit, smoothing, and overall comfort under a range of clothing.

Testers wore each style for hours at a time, assessing smoothing and support as they moved through daily activities—walking, sitting, climbing stairs, running errands, and light exercise. We paid close attention to whether pairs stayed in place without rolling or digging in, as well as how they felt over time. We also evaluated breathability, moisture control, visibility under clothing, ease of getting on and off, construction quality, price, and size and color range.
