Because there are a lot of men who play this game. Need I say more?
That probably accounts for a lot of it, though as I mentioned elsewhere there are women who dress in that "Leia's metal bikini" outfit so it's probably not all men.
Personally, I'm still waiting for a slave boy outfit just to humiliate Quinn and because it would totally suit him (for the lulz).
Well, it would
bring balance to the eye-candy options... though my eyes might melt if it's a male character w/body 4 though. Haven't started a Sith character, but noticed comments about the Sith Warrior's master being overweight. Would not like to see him
in something like that.
