I'm already on the prowl for a unique peplum jacket for Fall. To get you up to speed: peplum, defined. Now we can talk. Peplum dresses are already in stores, but for a less '80s, more tailored option, consider one of these cuties. I adore the sweet flounce at the waist and the cool fusion of this Topshop biker jacket — part moto, part peplum. This might be the one I've been waiting for . . .
