The mainstain of the runway -- the sleek ponytail -- seems to have retired back to the stable this season. In place of the simple style, hair at the Spring 2007 shows consisted mainly of detailed updos, loose buns and and loopy twists. From Stella McCartney to Emanuel Ungaro, these innovative updos ruled the runway. While these looks are a little more complicated to master than your basic low ponytail, they perfectly to complement the playful, feminine clothes that appeared in the collections. If you've been wondering about looks that would translate well from the catwalk to real life, I would say that these simple, but interesting hairstyles are an easy way to make yourself look up-to-date.
