Wasp waists. Dirndle skirts.  Ruffled, pushed up-bustlines. The late 50's/early 60's vibe of the hourglass silhouette inspired many fall collections. The mood was one part Joanie from Mad Men at Prada ( far right) mixed with one part Bardot in 'And God Created Woman' at Louis Vuitton ( far left).  Marc Jacobs (center) used the below-the-knee a-line in combination with slouchy jackets and sweaters. Whenever hemlines drop below the knee, skirts and dresses with a strong a-line shape are the easiest to wear. Forget long, straight skirts. The look is strict and impossible to wear. The a-line is the fashion ally of curvy women everywhere.  And the-throwback-to-the-50's use of wool flannel works for a sharply defined line because it's soft enough to drape and move with the body but firm enough to hold it's shape. 

Key to the look is a smooth, pleat free waist. Pleats plus a-line equals wide on anyone but models. The Talbot's skirt below is seamed diagonally through the hips to further enhance the shape on the body. They pair their skirt with a ruffled blouse. Might be a very wearable nod to the Prada dress ( above far right).
