Is there a video of Katherine Heigl presenting?
Yes, I posted it in her thread.
My best dressed list so far goes:
1. Marion Cotillard - Simply elegant, this dress was a hit or miss and for her, definitely a hit. The scale detail I'd imagine would be incredibly hard to pull off for any other actress, but she worked it.
2. Sarah Larson - Wearing Valentino couture must be a huge deal to her, hahah. Isn't she a cocktail waitress of some sort? I think the dress is so beautiful and it looked very nice on her.
3. Katherine Heigl - It's nothing new for her. I'm not saying she had the best
look (not so great makeup!), but the dress was exquisite and complimented her figure like no other.
4. Cameron Diaz - I don't believe in wearing light pink for the Oscars because it's far from an evening colour and so few can look nice in it, but the Dior was stunning. She looked great sans the last minute ponytail.

Would've looked a lot better if she pulled the ponytail under and had a messy bun instead.
That's it, really. This year's winners were well deserved, but the dresses? Kind of bland minus a select few, imo.
