Princess Eugenie and her fiancé Jack Brooksbank were pictured leaving Windsor Castle today, the evening before they tie the knot.
The couple are set to say “I Do” at 11am tomorrow, at the second royal wedding of 2018.
In the pictures, the 28-year-old could be seen smiling as she drove a car away from the picturesque venue.
Her groom-to-be beamed as he sat in the passenger’s seat beside her.
According to one royal watcher on Twitter, Princess Eugenie seemed to be wearing her Claudie Pierlot “Romilly” dress.
The social media user penned: “Eugenie appears to be wearing her Claudie Pierlot dress.”
The royal fashion finder and fashion editor went on to post a screenshot of the item.
Princess Eugenie has worn the designer number before, and it features both a polka-dot print and a floral pattern.
She was spotted wearing the outfit at a charity appearance earlier this year.
The designer ruffle-trim chiffon dress retails at £335.
Princess Eugenie also sported a pair of drop earrings, which another person claimed were AYA Mosi-oa-Tunya emerald earrings.
The earrings in question sell for £655, meaning if both Twitter users are correct, her outfit come to a total cost of at at least £990.
Writing on Twitter, the blogger penned: “At the Royal Wedding rehearsal in Windsor Princess Eugenie wearing her favorite AYA MOSI-OA-TUNYA emerald earrings £745.00.”(sic)
Elsewhere this evening, Princess Eugenie’s immediate family – her parents Sarah Ferguson and Prince Andrew, and sister Princess Beatrice – were spotted exiting the venue in another car.
The trio were all spotted in the same car, with Prince Andrew, Duke of York, behind the wheel.
As per tradition, it is currently unknown what Princess Eugenie will wear on her wedding day.
However, while the bride-to-be has kept her dress under wraps, she has shared a hint at what fans can expect.
In the September issue of British Vogue, the royal said: “I’m not telling anyone who is making it, but I can say it is a British-based designer.”
Royal wedding dress designer Sassi Holford, who designed Autumn Kelly’s gown for her wedding to Peter Phillips in 2008, shared her thoughts on what the princess may wear.
“I’m thrilled that she’s announced it’s a British-based designer,” she told Yahoo News’ The Royal Box, before adding “That does hint at the fact it’s not a British-born designer.”
