Best look on the red carpet:

Anges Varda
She looks very comfortable, doesn't she? Like DR Laura, she knew the Oscars would run late, so she wore her jammies. Quite original.
She's also in her late 80s and up for her first competitive Oscar. She should have a half-dozen by now.
Yes, I was surprised to see her here, but she is a film classic herself.
Actually, I think SHE looks terrific. Her ensemble is not something I would wear, but I personally would like to see a movement to more sensible, comfortable clothing for women. I don't mean jeans and t-shirts (although I wear them myself); I mean stylish clothing that is a pleasure to wear. Helen Mirren's gown looks like it might be.
