If you were Louis Vuitton, would you sue this artist?

No? That's probably why you're not Louis Vuitton. Because the company DID sue and lost. The court in the Hague said:

the importance of Plesner (freedom of expression through her work) outweighs the importance of Vuitton (protection of property). Using Plesner of the design is considered functional by the court and proportionate.

I. Am. Shocked. When did it become acceptable to deny corporate rights for any reason--let alone some milquetoast argument about art and freedom of expression? Fight back Corporate Earth!!
