Sienna Miller wore a Burberry Brit Bustier-Detail Eyelet Dress to the recent 2013 Up2Us Inaugural Gala held at the Tribeca Rooftop in New York City. This white, youthful dress is classic meets edgy (Sienna in a nutshell!) and has short cuffed sleeves and a relaxed pleated skirt. You can buy it from Saks Fifth Avenue and Neiman Marcus.
