Paris Fashion Week is off to a haute start today, with shows from Dior, Christophe Josse, Josephus Thimister, and Alexis Mabille. It's already looking like we've got a wild season ahead for hair if the look at Mabille's show is any indication. The models all had half their hair "dyed" (they were really glue-in hair extensions) in DayGlo hues, from bright pink and blue to this life jacket yellow. The other half of their hair was left natural. It was an interesting look, and definitely a bold choice, but would you ever want to see it come off the runway?
