What is it with the olden-times hats?

Charlie Chaplin or Odd-Job looked rather comical in a bowler hat, so why are the celebs rushing to wear them? What's worse, I saw a couple of stars spotted wearing one of these, ridiculous top hats! They just make you look like an old grandad - from a hundred years ago. In fact this picture above is Sienna Miller yesterday. See how the hat excentuates her big ears, crows feet and moustache? That's how you look celebrities. Don't do it!
