OK, I know it's nothing all that earth-shattering since long waves have been in fashion long before the Farrah Fawcett days. But this New Year's Eve, it was all about the soft cascading curl. Whether it was a more-refined look like Ashlee Simpson and Eva Longoria Parker or tousled and undone à la Molly Sims and Chloë Sevigny, the look was still sexy — and a little more inspired than pin-straight locks. Want some loose waves? Keep a large-barreled (at least one inch or larger) curling iron open and wrap your hair around the barrel for a few seconds and release. Is this the iconic hairstyle of the 2000s? We have one more year to find out, but I'm betting yes.
