Isabel Marant is the go-to label for Parisian cool girls, and it looks like Reese Witherspoon is also a fan.

The actress was spotted out and about in Beverly Hills this week wearing an Isabel Marant Fall 2009 tiered short print dress with frayed edges.

The chic dress was mummy-fied with a navy cardigan, but she added a cool pair of aviators and navy wedges to her look.

Net-A-Porter.com will be adding Isabel Marant to it’s already impressive list of designers from February 2010.

We can look forward to drooling online at the designer’s effortlessly hip pieces including boyish trophy jackets, slouchy pants and easy-chic mini dresses.

Lets not forget the studded suede pirate boots Sienna Miller wore last year which shot to #1 on many of our wish lists.

Those of you who got the Zara version were very lucky.
