The Best Shapewear (2025): Bodysuits, Briefs, and More

I usually wear a 10 or 12 pant size, and during my initial testing period I gained muscle and lost weight. I wore every piece at least twice, both around the house and out and about running errands or attending events. I made sure to bend over, stretch, squat, use the bathroom, sit down, walk around, take them on and off, attach and adjust any straps, and generally wear the pieces as I would in my daily life. I checked for comfort, stretching, whether the pieces rode up, rolled, or slid down, whether they were easy to breathe in, and what the silhouette of applicable pieces looked like under a tight slip dress. Next up I’ll be testing more brands including Spanx, Skims, Victoria’s Secret, and some affordable options from Amazon.
