Your Jeans Have Too Much Stretch
Stretch denim is a gift to women who shop for both comfort and style, but erring on the side of too much comfort can lead to lumpiness. "It's best to look for jeans with 2 percent elastic fiber," says Rothman. On the care label, you'll see Lycra, spandex or elastane. The right jeans will follow your silhouette, have enough stretch so that your legs won't look as if they're fighting to break free from your pants and, unlike denim with 4 percent or more elastic fiber, won't sag at the tush.
