Katy Perry, Kate Walsh, and Natalie Portman Wearing Polka Dots

Third time's a charm — three stylish celebs sporting navy and white polka dots makes this a polka-dot specific statement. It's a nod to something a little retro, and as you can see from Natalie, Katy, and Kate, there are more than a couple ways to wear it. Turn up the throwback appeal, as Katy Perry does, with a red lip and a floral accessory, or keep it simple and chic like Natalie. There's even a way to make your polka dots daring with sheer fabric and a few strategic cutouts à la Kate Walsh.
