The Countess of Wessex embraced fall fashion when she stepped out for a charity ball in London on Thursday night.
Sophie was channelling the current season in her autumnal-hued burgundy lace dress and matching bucket bag.
She paired the look with nude shoes and a chic updo.
The royal was attending the Great Ormond Street Hospital's Friendship Ball, where she mingled with British popstar Pixie Lott.
At the charity event, the royal mingled with popstar Pixie Lott, who is currently starring on Strictly Come Dancing.
The pair looked to be getting on famously as they giggled for the cameras.
Pixie wore a navy dress over a white shirt and completed the look with a pair of androgynous patent flats.
Pixie was taking a break from dance rehearsals to show her support for the charity. Last weekend, the pop princess waltzed her way to the top of the Strictly leaderboard, gaining 35 out of 40 possible points with her dance partner Trend Whiddon.
