Regarding Shokuhou's Vapor Wear: you'd think that with her assets she'd want to wear a bra for support, especially while she's in her relatively skimpy gym clothes. That said, she's only wearing them to suit the occasion, not because she's actually participating in any sports. What's more, it was mentioned earlier that she didn't return to her hotel last night, meaning she's probably still dressed as she was yesterday. And yesterday morning was when she performed the athlete's oath on international television... so she'd probably dressed to be as attention-grabbing as possible within the school rules.
