The 50-year-old royal - the daughter-in-law of Queen Elizabeth and Prince Philip - dropped jaws at the event when she stepped out in a £2,375 Mary Katrantzou gown.

The blonde beauty appeared to be in her element as she posed for photographs on the red carpet, before making her way into the star-studded ceremony held at Claridges.

The Countess - also known as Sophie - flaunted her trim physique in her mid-calf-length dress, which featured a small waist-band cut-out and lace detailing across the chest.

She completed the look with a pair of black suede heels and a matching bag, while her hair and makeup were kept simple, yet elegant, with a sophisticated up-do.

Meanwhile, the stunner - who is the wife of Prince Edward - previously admitted she had "caved in" to the demands of being a fashion-conscious royal in the public eye.

Speaking to the Daily Express newspaper, she said: "I recognise that I'm on display. I remember having a chat with somebody and them saying, 'You know you've got to recognise that this is part and parcel of what you're doing.

"When you walk into a room, yes people are going to talk about what you're doing there, but they're also going to want to know what you're wearing.' I sort of wrestled with that one for a little while and slightly caved in at the end of the day."
