here is the armor i just bought. its the forever panther suit.

YouTube - batsuit for sale

nmy question is, is there a local store i can get an undersuit to glue this armor to? i dont want to go online really, i would rather try one on in a store but i have no idea where to look for a spandex or lyrca undersuit.
