Remember when Diane Keaton as Annie Hall set the fashion world on fire for her adorable adaptation of men’s wear? Well, it’s back just in time for fall, the perfect season to break out blown-up houndstooth, plaids and pinstripes fit for an Ivy League campus or the boardroom. For a feminine balance, play with proportion like cropped pants, and details such as a cute collar poking over a pullover. Designers address all this new layering with oversized blazers and coats. After seasons of exaggerated platforms, they finally come to terms with sensible shoes, too. Girly ballerina flats also are pushed aside for loafers and oxfords.
