this is probably a bad idea but for the actual body suit, get a red one and spray paint the colors on using duct tape to be specific about areas you want painted
personally I don't think spray paint works well on cloth, depending on how strong it goes on and how much there is... Personally I've never spray painted a shirt, so I wouldn't know. You can actually DYE a shirt fairly easily using regular paint and tape, through some fairly simple processes, one girl actually did a speech about it during a class in my Speech I class.
Red morph suit, buy dual katanas off of
Truesword.com, dye the red morph suit with appropriate colors, use tape to make sharp/crisp edges, buy a big leather belt and put random pouches on it (bonus points, fill pouches with candy / fun stuff), etc.
All I can think of
