One accent seen on almost all the runways for spring 2012 was the peplum. A peplum is a flirty flare of fabric around the waist of a skirt, shirt or dress. Peplums originated in the 1800s and have periodically reappeared in fashion over the decades. Right now, they're in.
Warning: If you have large hips, peplums are not for you. The peplum is intended to accentuate curves -- not detract from them.
That said, there are two versions of peplums: fitted and flared. If you have an hourglass figure already, choose a fitted peplum. It won't flare out as much and make your hips look bigger than they are. If you want to add curves, choose a flared peplum.
