The 71-year-old duchess is no stranger to recycling her wardrobe.
During her July tour of Wales, Camilla wore a pale blue floral midi dress, which she opted to wear again this week.
As of late, Kate Middleton, the Duchess of Cambridge, has been a huge advocate for a recycled wardrobe.
The mother-of-three loves her off-white bespoke Alexander McQueen coat dress, which is one of her style staples.
In July 2015, she wore the structured-collared coat dress to Princess Charlotte’s christening, and it made another appearance at the Queen’s official birthday celebrations, Trooping the Colour, in 2016. She then decided to wear it again to Prince Harry and Meghan Markle's royal wedding.
