I thought Mari's plugsuit was green, then later pink, that plugsuit looks more red to me suggesting it could be Asuka's old plugsuit prior to that "see through number" she wares now?
Maybe the 12 o'clock is Hieda no Akyuu. Her garb seems to resemble that in this picture... post #681502 I'm no anime expert. Just throwing it out there because I decided to look for outfits that matched those legs. :3
The one labeled Tsukino Usagi, I find it hard to believe that one is her. it would more likely be Rini(not sure of the name the japanese version uses). 1. You see no twin tails. which even if they're not hanging straight down, you would be able to see some part of them even when she's laying.
2. Sailor Chibi Moon also has the same style boots(cresent moon included) as Sailor moon as well as having much shorter twin tails.
