Princess Diana's niece Lady Kitty Spencer enjoys glam night out

The glamorous Lady Kitty Spencer brought a touch of aristocratic power to a party in London on Monday night. Princess Diana's niece, who is the eldest daughter of Earl Spencer, looked a dream in a lace cream dress and black heels.

Kitty added an edge to her look with a black leather jacket, and kept her glossy blonde locks loose over her shoulders.

The 24-year-old was attending a bash held by Departures magazine, the exclusive publication distributed to American Express black card members.

Mingling with fellow blue-blooded folk, Kitty was joined by sisters Lady Violet and Lady Alice Manners, the daughters of the Duke of Rutland. Tom Parker Bowles, the son of the Duchess of Cornwall, was also spotted in attendance at the Maison Assouline bookstore in Piccadilly.

Kitty's outing comes after the blonde beauty was invited to the amfAR gala as part of Milan Fashion Week last month.

Wearing a gorgeous pink blush Jenni Button dress, Kitty was the picture of elegance. The high-society girl had a fairytale moment as she perched on the marble steps of the Museo della Permanente and showed off her exquisite gown in all its glory.

The dress has proved to be somewhat of a staple from Kitty's wardrobe. She wore the ruffled creation twice this year, to the Downton Abbey Ball at the end of April and the Hunt Ball in June.

Kitty is not the only aristocrat who loves to recycle. Her late aunt Princess Diana was a fan of reusing outfits – notably wearing a pearl-embellished Catherine Walker gown with a bolero jacket, which the Princess called her "Elvis dress", on at least two separate occasions.

The Duchess of Cambridge, née Kate Middleton, also reigns when it comes to reusing.

Unlike her royal cousins Prince William and Prince Harry, Kitty grew up away from the spotlight in South Africa with her mother Victoria Lockwood, her father Earl Spencer's first wife.

Kitty first caught the attention of the British media when she attended a memorial service for Princess Diana in 2007. Four years later she attended William and Kate's wedding held at Westminster Abbey in London, where she was seated next to her younger twin sisters Lady Eliza and Amelia.
