Pop industrialist Justin Timberlake is continuing to step it up with partner Trace Ayala (pictured above) and their clothing line William Rast (williamrast.com), introducing a full luxury men’s and women’s wear fashion collection for Fall 2008. An extension of the brand’s contemporary denim category, these lifestyle collections are being developed and designed in collaboration with Paris68 (paris68.org), the NY-based design consultancy firm owned by Johan and Marcella Lindeberg.

Calling on the services of the man behind the super-cool J. Lindeberg line (jlindeberg.com), is a smart move that will likely enamour the brand with an edgier consumer and no doubt increase it’s market reach. He will design the men’s collection while Marcella Lindeberg will design the women’s.

“I have always admired the modern designs and sophisticated esthetics of Johan and Marcella Lindeberg,” says Justin Timberlake, “I am really excited that we have the chance to develop these strong collections together and that my vision for a complete William Rast lifestyle brand is in the hands of two of my most favorite designers”.

Says Johan Lindeberg: “We are very excited about developing the William Rast collection together with Justin and Trace. For me, it is a great project to build a brand from an American perspective as a complementary challenge to J.Lindeberg. We have created a solid and long-term Collection foundation that truly reflects Justin’s and Trace’s background and lifestyle”.
