The key to pulling off a two-tier gown is finding a design that crops the top tier at an ideal spot for your body. A peplum (a.k.a. the short, flared piece of fabric attached to the waist of the dress) adds volume, so if you're looking to hide your hips, opt for a longer top tier. It's a tricky balance, but looks stunning when worn right.
