The Duchess and Duke of Cambridge walked the red carpet at the Odeon in London's Leicester Square with Prince William holding an umbrella to stop his wife getting wet in the rain.
Kate's nude and black floor-length dress by Alice Temperley won rave reviews from fans.
She teamed the long-sleeved gown with a silver bracelet and black clutch bag.
The lace gown was an echo of the Zara lace number that she wore to Gary Barlow's gig at the Royal Albert Hall at the end of last year.
