Last season’s flowered prairie dress slims down to more a wearable shape — a gentle fit-and-flare with a 30s meets 70s vintage attitude. Flounces are key, whether it’s a ruffled neckline, butterfly sleeves, a peplum waist or a deep gathered panel at the hem. Tiny covered buttons add more romance. Silky fabrics can be matte or shine, smooth or crushed, and floral-printed, striped, dotted or solid. While the feeling is demure, these frocks are not as modest as last season — slits show a glimpse of leg, and necklines are wide enough to drift off a shoulder for alluring dishabille. Hems hit at mid-to-low calf.
