Princess Anne, like many members of the Royal Family, knows the value in choosing clothes and accessories that become timeless staples in her wardrobe.
Like her father, the late Prince Philip, brother Prince Charles as well as Duchess Kate, the Princess Royal enjoys recycling pieces in her closet.
One of Anne's favourite accessories is her Adidas sunglasses. Anne has worn "Team GB" sunglasses from the brand for years and many of her outfits are finished with the Matrix-inspired frames.
The Princess Royal appears to have a few slightly different versions of the eyewear, but the thing that remains constant is their cutting edge shape, and distinctive white arms.
The Queen's daughter has worn her Adidas sunglasses to multiple Olympic events, races and to occasions casual and more formal.
Some have even dubbed Anne an under-the-radar sunglasses influencer because of her penchant for the futuristic sunglasses.
