Rearview spotted a Liquid Leggings trend on Polyvore. She says, "You can look super sleek and sexy with liquid leggings. They're also an affordable alternative to leather leggings...with added sheen." This look won't put a hole in your wallet (you can get a pair for $14 on forever21.com) and it's easy to pull off. Just pair up with a cardigan, t-shirt, or blouse. Hollywood's loving this trend, too!
