Hilary Swank, Amy Adams and Marisa Tomei sported dark blue.
I'm not feeling Hilary's feathery Gucci gown, it's too much and the whole feather hem thing is so 2009.
Amy Adams' sparkly cap-sleeve gown by L'Wren Scott evoked old Hollywood, especially with the hair but the emerald and diamonds were a bit of a turn off.
Marisa's dress was a vintage Charles James and it's not my favourite - the hemline is a little too much.
Natalie Portman wore a purple silk-chiffon Rodarte dress with an off-shoulder neckline. This particular shade of purple (more like plum) does wonders for pregnant celebrities! Jessica Alba wore a beautiful Marchesa gown to the Oscars in 2008 in a similar hue. I'm loving those swingy earrings from Tiffany & Co.
Scarlett Johansson wore a lacy Dolce & Gabbana dress with high neck and a drop down back (not pictured) - it's just too much lace for me.
