Collaborations are so the thing of today. Versace created a line for H&M and now Karl Lagerfeld has developed a line of clothing that will launch exclusively on luxury retail site Net-a-Porter.

Chanel's creative director Lagerfeld and Net-a-Porter's founder and executive chairman Natalie Massenet made the announcement on stage at the Le Web conference in Paris Wednesday morning.

The move is a huge investment for both companies. Net-a-Porter will be the sole carrier of 70 pieces from the Karl collection for the first four weeks after its January debut, and will be the online seller of the collection following that timeframe.

Lagerfeld will debut a rock-and-roll-themed collection at Couture Fashion Week in Paris on January 25, 2012, subverting the traditional retail cycle by allowing customers to purchase the entire collection in the same month it's introduced, rather than months later. 

Prices of the pieces will range frmo $95 to $450.

Net-a-Porter has already carried exclusive labels by Victoria Beckham and Matthew Williamson, but the partnership with Karl Lagerfeld is the biggest of its kind to date.
