Princess Anne's style is timeless, with her eye-catching outfits and glittering jewels making her an icon of royal fashion.
Not only does she have impeccable style, but she also isn't afraid to re-wear her standout pieces.
The Princess Royal attended the 30th Anniversary International Financial Review Annual Awards Dinner on March 17, stepping out at the Grosvenor House Hotel in London in a green paisley-printed dress.
She last donned the bright outfit in 1971 while accepting Sportswoman of the Year at the Sports Writers ball.
The frock was not the only item that Anne chose to re-wear from her own collection; she also sported a stunning choker for the occasion, a piece that she showcased at Prince William's wedding gala in 2011.
According to expert Maxwell Stone, who helms the jewellery retailer Steven Stone, the necklace features "four rows of pearls interspersed with 20 diamond bars all centred around an angual sapphire and diamond clasp."

"The piece was later acquired by Queen Mary, who frequently wore it throughout the 1930s," said Maxwell.
After Queen Mary passed in 1953, Queen Elizabeth II inherited the piece, however, the monarch rarely wore chokers and so gifted it to her daughter in the early 1970s.

Maxwell estimates that the choker's value is approximately £200,000, which comes as no surprise considering its staggering beauty.
As for the paisley dress, Anne has worn the outfit for multiple decades now, previously donning the look at the Palace of Holyroodhouse.

She has shown a preference for vintage designs, and everything from her elegant evening gowns to her daywear ensembles has proven that her style transcends the decades.
"I'm quite mean," she told Vanity Fair of her habit of re-wearing old pieces.

Anne is no stranger to imbuing deeper meaning into her jewellery either; the stalactite brooch she wore for Commonwealth Day celebrations in March heralded a nod to her mother, who had gifted it to the equestrian before her wedding to Captain Mark Philips in 1973.
She also brought out a pair of floral-inspired earrings on the day, which date back to 1984 when she wore them during a trip to Gambia.
