Louis Vuitton sues designer over Darfur T-shirt

Designer/Artist Nadia Plesner is being sued by Louis Vuitton for trademark infringement on her Simple Living T-shirt, where 100% of the profits from sales are donated to Divest for Darfur.
Nadia explains her motif:

My illustration Simple Living is an idea inspired by the medias constant cover of completely meaningless things.
My thought was: Since doing nothing but wearing designerbags and small ugly dogs appearantly is enough to get you on a magasine cover, maybe it is worth a try for people who actually deserves and needs attention.

Louis Vuitton's letter to Nadia reads in part:

Although we applaud your efforts to raise awareness and funds to help Darfur, a most worthy cause, we cannot help noticing that the design of the Simple Living Products includes the reproduction of a bag infringing on Louis Vuitton's Intellectual Property Rights, in particular the Louis Vuitton Monogram Multicolore Trademark to which it is confusingly similar. We are surprised of such a promotion of a counterfeit bag.
