Memorial Day cocktail party in your weekend plans? Olivia Palermo gave summery stripes a sophisticated spin just in time for your seasonal party schedule while celebrating Fabergé's NYC store opening last night. We love that she played it casually chic, adding evening shorts and a white tuxedo blazer to her basic tee. As always, Olivia perfected her style with attention to detail — her embellished blue Manolos offset the colors in her top and lent just the right touch of luxe. To finish, it's just a sleek black patent clutch and the style setter's signature statement jewels. Feeling inspired?
