Kate Middleton has been known to alter her outfits to fit her royal wardrobe, and she may have learned the fashion trick from her late mother-in-law, Princess Diana.
Elizabeth Holmes, a fashion journalist and the author of "HRH: So Many Thoughts on Royal Style," told Insider that Diana would have old clothes transformed into brand-new looks because she wanted to be both fancy and frugal.
"Diana benefited from the fashion scene before the internet existed because people didn't notice," Holmes said. "I thought Diana reworking her clothes was fantastic because it just shows how you can get many years out of a single dress."
Here are some of the outfits that Princess Diana had customized over the years.
