Who: Irina Shayk, Cristiano Ronaldo's girlfriend
What: A royal blue wrap dress (a Duchess of Cambridge favourite) paired with a black, waist-cinching belt and matching patent court shoes. She's just one step away from a Duchess Kate lookalike - her glossy long locks were left straight rather than curled.
Where: The launch of 'The Perfect Bra' at Intimissimi in London, 24 April
Bonus info: The Duchess was sans belt for her engagement photo, but if Irina's accessory looks familiar, it's from Kate's more recent royal blue outfit for her trip to Ipswich in March.
