Last night at the fancy 2008 Costume Institute Gala [1] in New York City, the women arrived wearing fabulous gowns [2] adorned with sensational accessories. Some of their beauty looks were favorable [3], and some left little to be desired [4]. One of the trends I noticed was the semi-laid-back approach to hair. Don't get me wrong, I am sure every strand was supposed to look like that, but there was a lot more looseness as a collective than I've ever noticed at a red-carpet event. Below are eight messy updos from some of Hollywood's leading ladies. What do you think of these hairstyles?
