Under the theme of 'Guilded Glamour', some of the world's biggest stars walked the steps of the Metropolitan Museum of Art in New York, providing show-stopping looks as well as raising funds for The Costume Institute.
From Kim Kardashian wearing the iconic dress that Marilyn Monroe wore in 1962 to sing Happy Birthday to President John F. Kennedy, to Blake Lively shedding layers of her Statue of Liberty inspired gown while walking the red carpet, this year's gala was a feast for the eyes.
Following the fundraiser, many celebs had a quick costume change before letting their hair down to enjoy the after party at at Zero Bond in New York City.
