Male vs. Female

So I'm part of the convention committee for a Sci-Fi con that hits our area this summer. As such, we were lucky enough to get first dibs on the new shirts to be available at con this year.

A) Artwork is so cool. Truly excellent.

B) For some reason, the guys shirts are sized larger than usual. Like, if you normally get a large, you can probably get by with a medium. It's okay though, because the women's shirts are sized extra small to make up for it. Like, as one person put it, maybe one of her thighs would fit in the large.

C) The people selling the shirts are less than pleased. This is totally not their fault in any way, shape, or form. They are warning people, to the point they both suggest a size and request you hold it up because the sizing is so crazy this year.

D) So, is it the fault of "fake geek girls" or is it the fault of the fashion industry forcing their skewed sense of norms on others? The women's shirts are smaller, cut tighter, and with a v-neck and slightly different fabric. The men's are larger, wider throughout, with a crew-neck and slightly more heavy duty fabric. They were charged the same to make them, so they are charging the same to sell them.
