With a cool twist on seasonal classics, Jessica Alba supplied the answer to "What does one wear to a Ralph Lauren Girls fashion show?" — or just about any Summer afternoon party. The actress and mom was a stylish guest at the label's kids' show with a ladylike fit-and-flare polka-dot dress and espadrille wedges. Lest you think this look is for moms only, the style pro outfitted hers with a worn denim jacket and a chic black-and-white Ralph Lauren Ricky tote for a trendier finish that's perfect for your own Summer party schedule.
