Although many people are always whining in these types of paintings that her armor isn't really practical, I'm still going for the theory that girls in little to no armor have the distraction value in battles.
"BEWBS" "Oy mate you fired that arrow into my foot!"
It's fantasy. Maybe not hardcore medieval fantasy, but the "wouldn't it be awesome if" kinda fantasy. And I favorited this because the quality of the pic itself is beyond heavens :3
Unless the men have just as little armor as the girls I'll buy the girls being next to nude. Otherwise I wouldn't call it "wouldn't it be awesome if" kind of fantasy, just "a sexist dream" kind of fantasy. Even fantasy got to have som logic even in the universe it takes place in. If the girls run around almost nude and the men have full armor and they both have the same "job", then it isn't logical, then it's just someones sexual fantasy.
