The most anticipated night in every A-lister's calendar is upon us: the first Monday in May means that the biggest names in fashion, film, music, art and beyond will be flocking to New York's Metropolitan Museum for the Met Gala, the Met Ball, the Costume Institute Opening Gala... Whatever you want to call it, the annual fundraising party, headed up by US Vogue's editor-in-chief Anna Wintour, can certainly lay claim to being the most fashionable soirée of the year, with a red carpet that easily surpasses any other (sorry, Oscars, but you just can't compete with Rihanna in Guo Pei couture).
This year's theme, Heavenly Bodies: Fashion and the Catholic Imagination, is certainly ripe for interpretation (though quite how far our celebrities will go remains to be seen). One of the first to arrive on the Met's infamous steps was event co-chair Amal Clooney. For her second Gala, accompanied by husband George wearing Giorgio Armani, the renowned human rights lawyer opted for a label that recently received the royal seal of approval: her show-stopping ensemble of bodice, trouser and rose-embellished train were by London-based designer Richard Quinn, whose LFW was attended by Her Majesty the Queen (who was flanked on the front row by Ms Wintour) last season.
See all the best looks from the Met Gala red carpet in the gallery below...
