Princess Anne was seen in a cream and navy outfit that she first wore in the late '70s or early '80s

When the royal family turned out in force for a special ceremony at Westminster Abbey on Monday, all eyes were on Meghan Markle and how she would fare – and what she’d wear to her first official engagement alongside Queen Elizabeth.

But it was the outfit of thrifty Princess Anne that has set sartorial-conscious tongues wagging – because it could be as many as 40 years old!

At the Commonwealth Day service at Westminster Abbey, Anne, 67, was seen in a cream and navy outfit that she first wore in the late ’70s or early ’80s, according to expert Joe Little. She even sported similar accessories (pearl earrings, brooch, gloves and navy bag) — not to mention the same hairstyle!

This isn’t Anne’s first royal rewear. In 2015, she wore a 35-year-old blouse and coat outfit to Royal Ascot that she was previously seen wearing on the balcony of Buckingham Palace in 1980.

The Queen’s only daughter is known for her no-nonsense approach to life and her public work. Anne is most comfortable outdoors, as an experienced equestrian, and hosts the Festival of British Eventing on the grounds of her home, Gatcombe Park, ever year. She even passed along her love of horses to her Olympic silver medal-winning daughter, Zara Tindall, who is currently expecting her second child.
