Kate Middleton left her princess tiara at home for a Wednesday engagement, but still looked every bit as stunning.

At the Creative Collaborations: U.K. & China summit at Lancaster House in London, held in honor of Chinese President Xi Jinping and his wife Peng Liyuan's four-day state visit, the 33-year-old Duchess of Cambridge sported a chic, semi-sheer, long sleeve, high neck, knee length eggplant Dolce & GabbanaGuipure lace shift dress with floral detailing, which retails for $3,495.

Kate paired the look with matching pumps and a cranberry velvet Mulberry clutch. She attended the event, held during a typical English rainy day, with husband Prince William, 33, who looked dashing in a dark blue suit and magenta, square design patterned tie.
