To be quite honest, I think she's looked terrible for most of the past several years and I love it. it's quite obvious she's having way more fun than those who are worried about how they look. She's wearing stuff she likes and I don't think she cares what others think about it.
I have noticed she seems to be wearing quite a lot more vintage lately. I wonder if it is because she's having a harder time getting clothes for free. There have been so many shakeups with designers, I doubt she still has the close friendships she had with the lead designers at the big houses.
