Thanks to Hedi Slimane's first collection for Saint Laurent, felt hats are more than just a head-warming accessory. They have the power to make your outfit. In fact, Bill Cunningham of the New York Times dedicated his On the Street column this past Sunday to New York City women and their new hat obsession. (One could say LE CATCH actually scooped Mr. Cunningham on this story, with reporting from my bi-coastal twin sister!) I rounded up some of my picks from Topshop (my sister bought this one and LOVES it), Lanvin (on sale but still a splurge!), Free People and Eric Javits.
