Just yesterday frockwriter mentioned that a number of Australian hair salons are reporting a spike of interest in the new “choppy” longer bob, aka The Kob, sported by Australian model Abbey Lee Kershaw (now the world number five according to models.com) - whose long, bohemian locks were trimmed by Chanel for the company’s recent Fall/Winter 2010/2011 ad campaign. Well perhaps those salons should be en garde: snapped a matter of hours ago at a Chanel cocktail party at New York Fashion Week, Kershaw has just died her hair platinum blonde. Yes we know there are far more pressing matters on the global agenda than a model’s hair colour change, but the fashion world does tends to exist in its own bubble. “OMG!!!! Abbey Lee has gone blonde!!!! LIKE BLONDE and looks amazing!!!!!” noted Canadian photographer and blogger Tommy Ton on Twitter – a Tweet, together with this Chanel party snap, above, taken by US model-dedicated news site Modelinia, that is rapidly spreading across the Twitterverse. Kershaw’s hair was coloured by high profile Cuban hair stylist Orlando Pita, Kershaw's mother agent Kathy Ward tells Chic frockwriter, but there are no changes to the style. We're now wondering if perhaps Chanel wanted to keep Kershaw under wraps until the soiree. Kershaw, Chanel's current advertising face and a star of every Chanel 2010 fashion show, did not show up at Tuesday night’s Fashion’s Night Out show at the Lincoln Center produced by Vogue (while compatriots Catherine McNeil, Ajak Deng and Julia Nobis did), even though she was featured in one of the FNO promotional videos.
