Ok, oil paint washed from hands, ready to surf through my favorite sites. I see an article in the nytimes blog site. Knockoffs vs. the real deal (the name of the Article is Designers Revisit Copyright Protection). The Article talks about what many of the designers supported in 2006 for copyright protection and the fact that many of those designers are planning on revisiting the Congress for another attempt.
So, I went back to 2006 and read what the hell happened in 2006. As many of you know, there are two types of items in fashion, the real deal and the steal (which is "inspired" from the real deal). While designers like Proenza Schouler, Zac Posen, Diane von Furstenberg are making pieces for $1,000, the same ones can be found at Zara, H&M and the Gap for not more than $50. While for some giving a $1,000 for a shirt can be too much and shops such as Zara and the Gap are probably their best choice, it may not seem so beneficial for the designers. They know that while some of their customers would always buy from their brands, there are people all around the world who are buying the same shirt for $50. Which also inspires the Steal vs. Splurge part of Marie Claire Magazine (which I presume Diane personally hates).
Accordingly, these designers want their designs to be protected under the copyright law just as a book or a song would be.
