Having a cool hat to polish off a look is key to celeb style. Actually, perhaps it’s a combination of fashion and function (ie, paparazzi shielding) that make them so popular in Hollywood. In any case, every girl should have a couple of cute hats on deck to help counteract bad hair days and to accent her wardrobe.

Eugenia Kim, hat designer extraordinaire, has been a celeb favorite for some time now. The likes of Cameron Diaz, Nicole Richie and Sienna Miller have all been photographed rockin’ her majorly chic and unique chapeaus and hair accessories.

We love this Muffy Matte Sequin Hat – which is part jockey, part diva – with its equestrian style and sequined and patent leather details. This accessory would perfectly polish off casual day-time looks and would make going incognito a bit more fun and fashionable. $275 available at shopbop.com.
