Looking at this photo from the J. Crew catalog, you get the feeling someone was desperately trying to find a way to make the gray dress on the right look good: “Maybe hold up one end? Stick out your hip?” But even a long-legged model looks dumpy in this combination of loose fit, empire waist, and voluminous skirt. What chance do the less sylphlike among us have of pulling it off? The narrow silhouette and lower waist of the dress on the left is a much more successful design—something to keep in mind if you want to try out this easy-breezy summer trend.
