To channel Fall's ladylike look, we're embracing boxy bags, midi-skirts, and most recently — sweet Peter Pan collars on our blouses, sweaters, and dresses. Unlike sharp menswear, these collars are soft, girlie, and hint at something a little more retro. We're pairing ours with everything from crisp skinny pants, wide-leg denim, and curve-hugging pencil skirts to balance the prim and proper feel. Of course, there are other ways to wear them — like on an edgier sheer LBD or leopard-print blouse, for instance. Click through to shop 10 of our favorite ways to wear the trend.
