The 81-year-old actress is making a statement against fast fashion.
It has warned customers not to buy from Amazon's third-party sellers.
Women won’t return items under £8.56 while men won’t return anything under £15.70.
The entrepreneur accused Missguided of using her name and image to sell lower-priced copies of outfits she had worn.
As people strive to be more sustainable, people have described the move as “disgusting, exploitative fast fashion”.
