Kate looked like a real-life princess in her white, one-shouldered, Alexander McQueen dress which she accompanied with simple accessories including a white clutch and diamond bracelet. Kate also wore an Alexander McQueen gown when she tied the knot with William in 2011.

Her standout accessory were her dangly pearl earrings, which reportedly belonged to the late Princess Diana.

The duchess took time at the awards show to honor some of the best British film stars in the industry, including actress Rachel Weisz, who took home the BAFTA award for Best Supporting Actress for her role in \"The Favourite.\"
