Venom Costume Suggestions?

Hey all, I randomly obtained a muscle suit and was trying to think of a costume to put over it. I'm 6" even without shoes but thin. This thing adds muscle bulk that goes somewhere beyond MCU Cap/Thor size so I think a Venom morph suit would be perfect.

I figure one of you mega fans has to have done this before. Any sites you would recommend buying from? Any oddities when trying to find the right fit over a muscle suit (it includes legs and chest)?

I don't want the Rami Venom but the classic suit, the 90's cartoon, or Spider-Man 2's version would all be fine.
