It's official: blazers are one of the hottest items in Hollywood. And to keep them fresh, blazers are taking on entirely new forms. There are bright blazers like cobalt blue, light blazers like soft pink, and even funky ikat blazers. But the sweetest of all is the polka-dot blazer, which Mischa Barton, Kate Mara, and Molly Sims have all worn in various colors and styles. And as you can see from these three ladies, they can easily go from casual to dressy with the right accessories. Mischa dressed her polka dots down with jeans and oxford flats, Kate dressed hers up with a sheer blouse and pumps, while Molly went in an edgy direction via leather pants. If you don't have a dotted blazer in your mix, shop one of our favorites below and wear them like these three stars did.
