His appearance here is not up to Charles's usual sartorial standards. This is s man who could emerge from a long walk in an equatorial climate looking immaculate in pressed khakis and well oiled boots. I have to think maybe his cancer treatments are very hard or he's training in a new valet.

William has certainly upped his sartorial game in recent months. Those blue slim-legged chinos he has favored seem to be making way for fuller-legged dress trousers and he's opting for newer suits, too.
