Well...apparently they do.
But we are not supposed to complain, because there have been some attempts to appease us when they came up with the so-called girlies, (or if you prefer ungrammaticality, 'girly's') made from stretchy material which often enough supposedly 'fit all'. Unfortunately these girlies are also usually only available for girly bands that girly girls love because the lead singer is so hot and girly.
What's worse, they also go by the name of 'baby doll' sometimes, which I think by itself sounds demeaning (I'm not a baby OR a doll, you idiots), but when googled leads you to a page called 'Dragonforce Ladies' Apparel: Dirty Power Metal Slut Babydoll'. Wow, Dragonforce really understands women and metal.
But I've heard...that there are decent girly shirts around, that they do exist, and I know it must be true because I own a few of these mythical creatures (don't tell anyone though). Sometimes girly shirts with logos of bands that even men would want to be seen wearing appear in obscure online webshops. Of course, there'll be no good picture of the shirt itself, but it'll be the outline of a girly shirt with the logo pasted on by some guy who simply edited the picture in Paint just to deal with the inconvenience of marginal female shoppers. And that's a bad move. Because I'll tell you something about women; we shop. And if there would be pretty pictures, and other things besides shirts (and I'm not talking about the slutty Slipknot tanktop which somehow always turns up everywhere), I'm telling you, we would go for it.
If something does not change soon, I am going to cut up one of your perfect square-shaped Devildriver manshirts and I will sew it into a dress - that's right, a DRESS. That's the thing with men and male-governed worlds; if you want something done, you'd better do it yourself.
