Considering how cute Jessica Alba looked in this Tory Burch polka-dot dress ($391, originally $489) and orange Tory Burch espadrilles, it's no wonder she was all smiles at an outdoor event in LA. Polka dots are the perfect way to show off your playful side, especially during Summer, so if you don't have one yet, be sure to score Jessica's exact dress now. Wear it with wedge sandals like the actress, with pumps and a blazer at the office, with a leather jacket to edge it up, or with a denim jacket to add casual cool. You can even swap the tie belt for something colorful for even more pizzazz. Its neutral colors are a great canvas to play around with all Summer, then come Fall, pair it with tights and booties for a cozier feel.
