I've read both those articles when you brought Angela into the discussion. I'll keep my opinion, that HM has done nothing to help Beatrice out of a rut, which again in my mind, never existed.
The point that you made was that there was no need to ask HM before Beatrice and Eugenie commissioned Angela Kelly to design their dresses and I'll stick to my opinion that as HM employs Ms. Kelly plus four more aides to cope with her wardrobe alone, any additional commission has to be agreed by her. And even if not, it would be extremely rude not to ask if it was convenient for her that her personal assistent works for someone else, even if that work was for her own granddaughters.
