New Years is a time for parties and gathering with friends to ring in 2008. Many events are formal or semi-formal and these call for some appropriate hairstyles. If you like to pull your hair up into an updo then take a gander at these. If you love the current retro interpretations then one of those ideas my be your fancy. We have Jessica Simpson with a 60's bouffant do, or Hilary Duff with her version of 70s style, or, if you prefer to wear your hair down, check out Shandi Fiennessy. Kimberley Walsh has a great look with a headband. We have a great picture of Brad Pitt and Angelina Jolie in formal attire.
