The Duke and Duchess of Cambridge attended the first awards ceremony for his Earthshot Prize, which champions solutions to protect the planet.
Both opted to recycle past red carpet looks.
Catherine recycled her Alexander McQueen lilac gown which she selected during her first ever royal tour of Canada and the US for the 2011 BAFTA Brits To Watch event.

Which do you prefer?
Prince William opted to re-wear his velvet green Reiss suit having worn it back in 2019 to an event supporting Centerpoint.
He also opted to give it a fresh spin, by opting for a black turtleneck.
Their choices were in-keeping with the ethos of the event, for which guests were expected to wear, or re-wear, outfits with sustainability in mind.
