Hats are a great way to simultaneously accessorize an outfit or camouflage bad hair days--just ask Hilary Duff, Rihanna and Fergie, three A-listers who are known to top their mops with fashion-forward headwear.

If you’re new to wearing hats, the unique selections in this cluster are a great starting point. Green goddesses will love the Trilby Hat, which is made from upcycled coffee sacks; it looks like a woven version of the black fedora Hilary Duff sports in the gallery. And Harajuku lovers will swoon over the tiny pillbox hats found by our very own TrendHead.

Some designs are a bit more off the beaten path, however. Hilary Duff, Rihanna and Fergie all pull off the slouchy beret look, but if worn wrong, this French fashion can come off as downright boring. Nagi Noda’s animal hair hats and the big-brimmed Kentucky Derby hats are sure to attract some attention at special events.

Whether your tastes trend more towards Hilary Duff’s classic black fedora or Brian Lichtenberg’s futuristic hair-toppers, you’re sure to find an accessory you’ll love in this gallery.
