Marx had one. Costumes of the World or something like that. White plastic; full dress head to toe, "golf"berret, kilt, knee highs, etc I think there is a female dancer too...?; might be Irish.
Not exactly sure of the size. I'll have to try and recall where he is hiding (I looked aroud real "quickening" like though. I'm just not ready to loose my head searching for that One 😐 😏 😂)
Military would probably be more life-like. The McMarx pose is a sort of bow legged, or slightly squated stace. Like a guy blowing into a tuba with all his might. (Not awful, decent detail; just not a "natural" looking stance imo.
