Well, the DOA women are basically like a series of caricatures on "hotness." I mean that in the sense that the common things that could be considered sexy about a woman in some way or another is scaled up to ridiculous levels. Long legs, big breasts, curves everywhere. Notice that for women who can apparently kick your ass six ways from Sunday, there's no muscle tone at all? Of course not -- significant muscle tone would break up the smoothness of curves. Logic would tell you that if a girl had to fight while having a chest that makes her look like part of a melon-smuggling ring, she'd probably bind them down with bandages... oh, but obviously, we can't have that -- bouncy, perky breasts are all part of the game. Notice that most of their outfits have artificially high waists? Of course -- it makes the girl look like she's got legs up to her face (which for the most part is anyway true). Things like the smooth low-variance gradation of color across the surfaces are all there to evoke the effect of appearing delicate (in the same way you'd look at a porcelain doll as delicate) and driving in that whole "fairer sex" image.
