American Apparel : shocks...

American Apparel introduced a t-shirt with the image of "menstruation" on it... Like expected twitter is exploiding with comments.
For me, I like it,  I love to shock with something as simple as a t-shirt. I believe there are other more negative t-shirts on the market...so why the big news.
It's something we (women) all have and hate!!!
Some t-shirts show boobs .... this is a drawing, I don't get it! People sometime just are "want-to-be-saints".
