Lady Kitty Spencer lit up the Cannes Film Festival all weekend, and we have been in awe of her red carpet looks.

On Saturday, the mother-of-one looked like a Hollywood movie star as she sashayed in front of a sea of photographers, wearing a beautiful sequin dress with fashion-forward cut-out detail.

With her iconic icy blonde hair slicked back and glamorous, showstopping makeup highlighting her pretty features, the 34-year-old sent flashbulbs popping as she posed up a storm in her statement Dolce & Gabbana purple gown.

Princess Diana was known for adoring the colour purple, wearing plenty of lilac-loving dresses and blazers with the bold tone over the years. Many would say it was her favourite shade to wear, and it always looked magnificent with her blonde hair.

In 1997, a few months before her tragic death, Diana was seen at the Red Cross headquarters in Washington, wearing this charming Catherine Walker lavender-toned suit, which she styled with a classic pearl necklace and Chanel toe-capped shoes.

A year earlier, in 1996, the mother of Prince William and Prince Harry was famously pictured at a gala dinner at the Field Museum of Natural History in Chicago. Her show-stopping, jewel-toned purple dress was designed by Versace, and she topped the look off with Jimmy Choo heels with a pearl choker.

Kitty's comments on Diana

Kitty was only a child of six when Diana passed away. Previously speaking to Hello! Fashion, she touched on her late aunt’s influence in the fashion industry. "I think she’s iconic and I suppose it’s such a wonderful thing that her fashion influence is still enduring today. She was a great ambassador for British fashion."
