Leave it to the eternally chic Sienna Miller to make a ruffled confection of a dress look utterly cool. Tiers of flouncy fabric require precision styling in order to pull off successfully (i.e. not look like a pageant contestant). We’re taking cues from Ms. Miller who paired her frilly cocktail dress with barely there metallic heels and minimal jewelry. If you feel compelled to wear earrings, opt for modern hoops in lucite or acrylic and be sure to steer clear of chunky, costume-y baubles. For glam, keep your makeup fresh with neutral lipstick and glossy black mascara and your hair slightly tousled à la Sienna’s effortless do. When in doubt, style minimally and let the ruffles do the talking.
