@animenerd Yeah, I think you're right. After reading many reviews and some tutorials since last night most of them seem to be saying the same thing.
@Kelley Agreed, I have considered wearing shapewear under anyway, just to smooth out some of the, albeit natural, folds / curves. Also, thank you for some of your other contributions to bustier / corset threads before this. I read several yesterday and you offered some really useful ideas. I can't remember if it was one of your comments or just a reply you made to someone else who mention it - but I will definitely try contouring with make-up. I'm going to get some bronzer or a brownish color this weekend and test it out to see what will give the right illusion.
@Penlowe Holy cow. Some of the handmade bunny suits I saw on deviantart were similar, or at least match the description. Couldn't fold them, some of them even looked like they'd stand up on their own. Not sure I need -that- much support, but I don't want to be a victim of gravity.
Thank you everyone - I will let you know what I come up with. In the mean time I did find some useful links to similar costume pieces I may consider (thought I'd share in case anyone else is interested):
