It is one of the biggest fashion events of the year but not every star hit the mark with their fashion choice. Here we look a the best and worst dressed at this year's Met Gala in New York.
The Worst Dressed
Solange's outfit was compared to "cupcake holders" or "a decorative napkin" by some observers. Her lemon yellow-coloured costume was interpreted by some as a tribute to her sister Beyonce's new album Lemonade.
Madonna's outfit was the most talked about of the night but failed to impress many people, including Piers Morgan who tweeted: "One word: YUK."
The former Black Eyed Peas star wore a black bowler-style hat with a visor attached, with one critic comparing him to a "futuristic beekeeper".
The Best Dressed
Beyonce, who arrived on the red carpet without husband Jay Z, impressed fashion critics with her latex gown from Givenchy.
Keith Urban couldn't keep his eyes of wife Nicole Kidman as she sparkled in a dazzling gown from Alexander McQueen.
Emma's look not only impressed the fashion critics but also proved to be eco-friendly. Her stylist revealed the outfit was produced with fabrics made from recycled plastic bottles.
