I like what Kate's wearing today. TO be honest, I've loved her look generally - it's felt professional, attractive, flattering and appropriate (although I hate the word appropriate in this context). She's looked gorgeous without weird issues about where the outfits come from or whether they're right for the moment etc.
As for Harry, I actually have a great deal of sympathy for him and every time I hear people say that his war on the press is ill advised my hackles rise. There's a huge difference between accepting the reality of living a life of privilege in the public eye and the undeniably hate-filled campaign the media have waged against him and, more noticeably, Meghan. And accepting a certain amount of interest when you're out and about privately is very different to the press being extremely intrusive - eg I saw something on Twitter (admittedly, no way to know if it's true) that suggested they'd been trying to get into the British Consulate with long-lenses to see Archie while in Cape Town.
As for moving away - I don't think that the very low chance of him becoming regent down the line is a reason not to. it's the 21st century, if, god forbid, something happened to both his father and brother, he could relocate back to England to be close to his nephew pretty damn quick. Also, no idea of legalities, but at this point, I'd have thought that Kate could act in George's stead of necessary.
