It’s the Royal Order of Queen Elizabeth II, as the Royal Ladies don’t wear medals, the reigning monarch gives them out at their discretion. It won’t be given any more and will now be the Royal Order of KCIII should he choose to give them out.can someone please explain the broach and yellow ribbon Katherine is wearing on her evening dress. What is it? Why is she wearing it? I’ve seen her and Camilla were similar and don’t know what they are for.
