Nothing captures resort informality better than a billowy dress. For next season, designers propose effortless smocks and frocks in delicate shades of white and ecru, adding an unbleached purity to the look. Scarf-tie necks, drop shoulder seams and side slits provide even more ease, and crochet-doily appliqués add dimension. Silhouettes range from shirtdresses to caftans, and lengths go from midi to maxi. The look can be achieved with 2-piece sets as well.
