Mary Kate Olsen wore this look to the Met Gala in 2007. Olsen is one of the aughts most important trend setters, and her glamorous, decadent take on goth is surely one of the most imitated on the red carpet. This feathered gown by Lily et Cie by Rita Watnick is one of the most memorable 'glamorous gothic' looks of the past 10 years. We wish we could own a dress that beautiful! Olsen toughened up the look (another aughts trend - tough belts and pretty dresses) with an Azzedine Alaia belt.
