I don't think the Erdem was dreadful, and it's nice to see her in a softer look, but It's a bit meh. Much too seventies for me. Having said that, I remember how popular Laura Ashley's dresses were so I can see that to a younger eye they might appeal when it's first time round.
I think some of you are being a bit mean about Kate's accent. Most of us only hear her when she is speaking publicly or being interviewed. She clearly isn't comfortable and her words tend to disappear. I'll bet she sounds entirely different when she's relaxed among friends.
It's also my experience that men do sound a lot less 'posh' (hate that word) than women wherever they went to school, it's all part of bloking themselves up. Girls just want to fit in with their peers.
