This reminds me of one of my favorite strips out of Van von Hunter, where a guy shoots an arrow at a Necromancer and it bounces off her platemail bikini, to which she remarks "whew, good thing I was wearing my armor."

The archer is berated by his companion and then they are overrun zombies.

Anyway, the point of this is that female outfits in RPGs are generally ridiculous. The reason? Sex appeal.
