While we were focusing on Milan Fashion Week and the Emmys, Natalie Portman debuted a platinum blonde hairdo on the red carpet on Saturday evening while attending Van Cleef & Arpels Dinner for LA Dance Project in LA.

She becomes the latest celeb to fall in love with Raf Simons’ Christian Dior Fall 2012 collection, which was the second Dior Couture dress to hit the red carpet this weekend.

Her floor-length white bustier flower-embroidered gown was styled with Van Cleef & Arpels jewels and a red velvet clutch.

The dress was also styled with hot pink shoes, but only Vogue.com have that picture.

I much prefer the dress on the runway, Natalie doesn’t quite have the height to make it work. The skirt looks a tad deflated on Natalie, which is one of the reasons why it appears longer in length.
