Gah, so this is where my thread went. My bad, I didn't know it was already brought up.
Yep, the concept art seems to be faithful to the anime except for the outlined waistline. It makes the girls look like they're wearing bikini bottoms over their suits. Regardless, I'm sure this movie will be a lot better than the last anime-to-live action conversion I saw, Fist of the North Star....(ugh).
