The photos, which were taken in November at London's Kew Gardens by photographer Paolo Roversi, are worthy of a future Queen. In one black-and-white image, Kate delivers a vintage vibe in an elegant chiffon Alexander McQueen gown. Her traditional side profile pose shows off her diamond and pearl drop earrings, which belonged to Princess Diana. Her iconic sapphire engagement ring, which also belonged to her late mother-in-law, is also on display. And instead of her signature bouncy blowout, she opted for more refined curls. Kate goes for full-on glam in a second photo that shows the beaming royal in a one-shoulder red satin dress (also by Alexander McQueen) with a dramatic sleeve and pockets.
