Is the Queen of England taking a page from Duchess Catherine
? The royal matriarch has been recycling a plum coat for years now, wearing it most recently on Monday for an official outing in Windsor (right) as part of her Diamond Jubilee tour
The coat's first appearance came on Christmas Day 2006 (left), when the Queen stepped out for church with her family. She also wore the piece – designed by her head dresser, Angela Kelly – to the Giant Rugby Ball in London in November of 2008 (center).
On Monday, the Queen paired the coat and matching hat – also recycled from her wardrobe – with black gloves, a dainty black leather purse and a diamond brooch.
According to a Palace spokesman, the royal matriarch has a purpose for repurposing her clothes. "The Queen is very conscious of the economic climate," he tells the U.K.'s Daily Mail
. "She is always looking for ways to keep costs down."
Similarly, her granddaughter-in-law has been known to re-wear clothing, often shopping from her own closet and even sharing items
with her sister, Pippa Middleton
, and mother Carole.
The budget-conscious Queen was greeted by more than 1,000 people Monday, welcoming her to Windsor as part of her Diamond Jubilee tour of Britain.
According to the Daily Mail
, she met with school children, residents celebrating 60 years of age and couples marking a diamond wedding anniversary this year. Wednesday she'll visit the counties of Avon, Somerset and Devon, with her husband, Prince Philip, in tow.
