9. Women's Underwear
Now, considering that you can buy a whole variety of clothing featuring the images and logos of the show, I'm not too surprised that it would eventually move into underwear. Much like someone running their fingers through a promotional catalogue and simply ordering everything out of a single section. This isn't to say that there aren't female Star Trek fans, because we know there are. Just I wouldn't be surprised if the number of female fans buying these for themselves wouldn't be greatly outnumbered by the male fans buying them for their non-Trekkie girlfriends and thinking it was a good idea at the time.
