Duchess of Cambridge Kate Middleton is a great role model - because she wears the same outfits several times, according to Sheffield University experts.
Researcher Dr Natalie McCreesh said: “She often re-wears the same items and shows how you can make the same dress look like a new outfit just by changing accessories.
“She even borrows clothes from her mum and sister, buys from outlet stores and consignment shops.
“All these things might not immediately seem environmentally friendly but they add up to make a huge difference. It’s about looking after what you already have and getting more use of what you do buy,” she added.
Dr McCreesh was speaking at a meeting of fashion experts in London.
