How to Get the Olsens' Ultimate Vintage Style

From Ieishah Clelland, former About.com Guide

MK and Ashley worked the red carpet at the Elle Style Awards in London as honorees in complementary but contrasting mini dresses with sheer trains. Only Ashley's dress is vintage--Christian La Croix. This use of sheer adds a touch of the conservative to the fitted mini-skirted dresses.

The Lesson?
See a look on the runway that you'd like to recreate? Bet on vintage. You can always (always!) find vintage versions of contemporary couture.
