With the wig try teasing it out a bit before using a bit if hair gel or wax..that should help to stick it out. And if you want to ends to spike more, use a touch or gel/wax and use it on the ends..
With the bags under your eyes to look natural, I would suggest using eyeliner, dont put to much though, and smug away. Or maybe black eyeshadow could work...
And to help flatten your chest, try bandages or something like to bind them down...
Hope any of that helps..=]
