Princesses Beatrice and Eugenie enjoyed a night out with their mother, Sarah, the Duchess of York, as they attended the Masterpiece Midsummer Party on Tuesday night.
The event, held in aid of the Marie Curie Cancer Care charity, saw a host of high-profile celebrities in attendance, including Hugh Grant, pregnant model Caprice Bourret and James Middleton's girlfriend Donna Air.

Beatrice, Eugenie and Sarah chose a classic and smart look for the night. Eugenie, 23, looked radiant in a purple dress that fell just above the knees.
She was seen enjoying spending quality time with her sister and mother, before she reportedly heads off to New York to work at fashionable auction house Paddle8.
Beatrice, 24, and Sarah opted for a darker look, both complementing each other in black. The eldest York sister wore a long-sleeved black dress with ruffled skirt, while Sarah wore a classic black dress. The trio accessorised with small clutch bags and dainty jewellery.
Sarah and Beatrice happily chatted away to Ronnie Wood and hostess of the party Heather Kerzner, and stopped to have a group photo.
Model Donna arrived without her boyfriend James, who is preparing to become an uncle to older sister Kate Middleton, due to give birth to the royal baby in mid-July.
Donna looked elegant in a white dress with pretty lace detail, and matched her outfit with a small, cream handbag.
As a close friend of Princess Beatrice, the two are often seen partying together at private members club LouLous.
Caprice, 41, also attended the charity event and turned up with millionaire partner Ty Comfort at her side. The model miraculously became pregnant for the first time in her life after having suffered a miscarriage, and will give birth in autumn.
She turned heads in a bold, red mini dress that showed off her baby bump.
The guests showed their support for the charity by placing bids on items. Hugh Grant bid on a few things but lost, while Nick Candy had more luck and won a pair of earrings.
