Bell sleeves and ruffled details burst onto the scene during the fall, but they've proven to have true staying power emerging as THE biggest trends for spring. Pair a bell sleeve blouse with an A-line mini and slides, your favorite distressed denim or even a wide leg pant for extra drama. Ruffled details are showing up on blouses and dresses alike. Either way you spin it, wearing one or both of the above will instantly elevate your look.
