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.
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.
