Man, but Kate’s really working the whole "Buy my stuff! Please buy my stuff!" thing, isn’t she? Here she is at the Costume Institute Gala wearing a black version of the orange/red dress she wore in Topshop’s window last week, and accessories with her near-constant companion at the moment, Sir Philip Green, who’s probably so worried that the money he’s invested in Kate recently could go straight up her nose and bring his brand into disrepute that he seems to be accompanying her everywhere. Still, it’s better than being accompanied by Pete Docherty, so have a Fashion Police gold star, Kate, you’re looking good…
