True fashionistas know the fashion event of the year isn't the Oscars but the Costume Institute Gala. Last year's brought us one of the best dresses of the year and this year promises to be truly fabulous, with the theme Superheroes: Fashion And Fantasy how couldn't it be?
Diane von Furstenberg has designed custom dresses for Ashley Olsen and Mary-Kate Olsen, who will attend as her guests. The event will be hosted by Anna Wintour with Giorgio Armani, George Clooney and Julia Roberts.
The most exiting red carpet of the year is on Monday.
So are you ready?
