Well, the only real problem is you want to be a scantily clad character without actually being scantily clad. Hur hur. Are you good at sewing? Cause a tube top might work, but you'd have to cut and sew it so the shape was right, and to give it all the strappies it needs. Also, I hope you have small boobs, because when you wear stuff that isn't already supported by your neck or shoulders, gravity tends to get the better of you if you catch my drift. xD
