There’s a new way to show off your curves: leggings that lift and sculpt your behind. These ruched ass leggings, aptly named “scrunch butt” leggings, have been making waves online—most famously on TikTok—with thousands of rave reviews and a devoted following, including celebrity fans like Lizzo.

The bestselling pair from Amazon (also sold in longer leggings and cropped options) has a textured honeycomb pattern with a seam that’s designed to lift the butt. According to the brand, the “booty-boosting” effect is achieved thanks to four-way stretch and ruched tailoring that accentuates the curves.

While many who’ve reviewed the leggings on TikTok say they do a good job, one thing that many reviewers mention is that the texture of the leggings can be too much for some, reminding them of reptile skin. In addition, some find that the scrunched-up fabric doesn’t support their backside during strenuous workouts, so they’re better suited to lounging or light exercise.

If you’re looking for an alternative to the Amazon leggings that have everyone buzzing, check out this high-waisted pair from Lululemon that’s made of sweat-wicking fabric with four-way stretch and comes in a variety of lengths. It’s also been featured on Good Housekeeping and has thousands of five-star reviews. It’s a squat-proof option for both low- and high-impact workouts, and has an elasticated waistband that smoothes the tummy and is incredibly soft on the hips and thighs. The only downside: It doesn’t have the same “scrunch butt” effect as the leggings on Amazon.
