Life is one big party for Lady Kitty Spencer! The niece of the late Diana, Princess of Wales headed out to her second London Fashion Week bash on Tuesday evening. The cousin of Prince William and Harry attended the LOVE Magazine event at Louolou's private members club. Kitty shocked fans with her outfit – which was a big change for the model. Instead of her favourite palette of pastels and floral print dresses, she wore a bold red and yellow slogan T-shirt and sexy lace-up skirt! The entire outfit was from Dolce & Gabbana – Kitty is a model for the Italian brand, so it comes as no surprise – she stays loyal to their designs. The skirt was a form-fitting creation and was made in a striking, oxblood hue coming complete with a hook and eye detail and the sides and hem. Priced at £1350, the risqué number had a certain Kardashian style element to it. The Bulgari ambassador added a T-shirt, also by D&G which had 'SANTA MODA' emblazoned over the front, costing £250. Her arm candy of choice was a metallic shoulder bag and sky-high metallic heels completed the look.

A new look for Kitty!

Lady Amelia Windsor was also at the party, but she went slightly more casual with her attire – rocking a black slip dress that featured a ditsy floral print. It had lace detail at the bust and is by Michael Kors. She added layers of gold chains and strappy black sandals as she posed for pictures.

Members only hot-spot Loulou's is a firm favourite amongst the royals. The multi-story venue is situated in Mayfair's Shepherd's Market and is known for its gorgeous décor – lots of baroque finishings and art deco touches – and there's even a chic courtyard.
