"Put a lid on it" takes on a whole new meaning this season. Whether or not you consider yourself a hat person, with so many shapes and colors to choose from, you're sure to find a style that will cover your pretty little noggin' to your liking. Marc Jacobs took a vintage, lady-like direction on the trend, with bon-vivant multicolored hats with knit crowns. Nina Ricci brought back feathers, Michael Kors did fur, and Proenza Schouler did 1920s-inspired caps. Fedoras or riding cap, Russian princess-y fur or fuzzy knit, it's time to top off your look with a hat of some sort. Get inspired by the mad hatter himself, Philip Treacy (www.philiptreacy.co.uk).
