Kate Middleton‘s latest outfit is more disco than duchess.
The 37-year-old-royal, who’s on a surprise two-day trip to Northern Ireland with Prince William, headed to an event at Belfast’s Empire Music Hall wearing a green Missoni dress ($2,480) featuring metallic lamé, a pleated skirt and long sleeves.
Middleton paired her mint-hued midi with taupe suede pumps, a matching nude clutch and casual curls, while Prince William opted for a suit sans tie.
The sparkling outfit was a playful change from the Duchess of Cambridge’s daytime look; earlier, she wore workout gear and sneakers under a red Carolina Herrera coat dress to play outside with local children.
The party-ready dress was a fitting choice for the evening’s activity; inside the venue, Middleton and Prince William took turns pulling pints of beer.
