Last year's Met Gala (the annual fundraising event held in New York's Metroplitan Museum of Art's Costume Institiute and hosted by US Vogue Magazine) sticks in the memory mainly for Rhianna's "omelette" dress, which sparked a million memes online.
This year, the theme was "Manus x Machina" and which was interpreted in myraid ways. Metallics were the most obvious and popular choice.
Kim Kardashian stuck with her favourite designer of the moment, Balmain, whilst rising Instagram star and sister of Lucky Blue Smith, Pyper went in custom H&M. Sticking with the silver theme was a radiant Brie Larson in tiered Proenza Schouler and Cindy Crawford, also in Balmain.
The other big fashion stories were capes, as seen on Mackenzie Davis (in Altuzarra), Sophia Sanchez (in Dolce & Gabbana), Nicole Kidman (Alexander McQueen) and Blake Lively (Burberry).
Other outfits of note include both Willow Smith and Alexa Chung in trouser suits, Lupita Nyono'o looking gorgeous in green Calvin Klein (with the best hair-do of the night!) and Claire Danes in a Zac Posen glow-in-the-dark number!
