Prince William just held one of the most important events of his life, the first-ever Earthshot Prize Awards. So, naturally, he made sure to bring his fashion A-game.
The Duke of Cambridge stepped onto the red green carpet for the event at Alexandra Palace in London on Sunday. Accompanied by his wife, Kate Middleton, the duo simultaneously turned heads with their unique, yet equally stunning ensembles. While the duchess opted for a lilac gown by Alexander McQueen, which she previously wore to a BAFTA black-tie event a decade ago, William opted for a greener look.
