It's these easy cotton poplin dresses we're falling for this year. Here, a fit-and-flare silhouette meets elbow-length puffed sleeves with pockets at the sides (because who doesn’t love pockets?) Fit & Flare: Relaxed shoulders, straight through the bust, defined waist with a flare skirt. Scoop neck and pull-on design. Elastic smocking at the waist. Side seam pockets. Unlined.
