Rockers are channelling stylish selves in new clothes ranges

First, there was news of Liam Gallagher (Oasis) starting his own fashion line, 'Pretty Green.' Then, avant-garde label Comme des Garçons teamed up with The Beatles for a capsule collection (sold at Dover Street Market). The latest example of 'music rocking fashion,' however, is Franz Ferdinand writing a song for Dior.

According to reports by Women's Wear Daily, the French fashion label is planning to premier its first music video January 14th.

Part of the promotional campaign for its 'Lady Dior' range, the label's spokesmodel and Oscar-winning French actress Marion Cotillard will portray a woman who transforms into a glamorous singer at night, performing Lady Rouge, a song specially written by Franz Ferdinand for the campaign.

The news follows the announcement that rock band Kings of Leon would soon release their first fashion line in collaboration with Paris-based agency Surface To Air, which was previously involved in lines for graffiti artist Banksy and electro-pop band Justice.

While 'rockers' are a rather new feature in the world of trendy collections (as opposed to tour t-shirts), fashion/music collaborations have become commonplace in pop music: Lily Allen performed at a Chanel fashion show, stars in the label's ads and even announced she would quit music to focus on her fashion career instead, stars such as Beyoncé and Rihanna are gracing the covers of fashion magazines and sit front-row during fashion week, and Lady Gaga is maybe the first singer who truly unites both industries.
