Since its genesis in 1971, The Metropolitan Museum of Art's annual Costume Institute Gala has been the most fashionable event in the red carpet calendar. Sure, The Oscars has its moments, but when you put infamous ex-Vogue editor Diana Vreeland in charge of an event and invite everyone who's everyone in the fashion industry, the style bar gets raised so high you can hardly see it any more. 

Since 1995, Anna Wintour has acted as chair, and the incredible effort put in over the years from Alexa Chung, Diane Kruger, Sienna Miller, Naomi Campbell, The Olsens, Kate Moss, Giselle, Sarah Jessica Parker, Cara Delevingne, and anybody else with a credit account at Bergdorf's, proves that only the most amazing outfits will do when you're invited out by Vogue's big-boss.

As we get ready to take a look at what the stars pull out the bag for this year's Beyond Fashion: Charles James themed event on Monday night, let's take a look at the 70 most memorable looks from years gone by.
