An outfit donned by either losers, freaks, or Peter Parker. One can tell if the costume is worn by a loser or a freak, as they will have attached false legs to it to simulate the eight legs of an arachnid. On the other hand, when the costume is worn by Peter Parker, he then becomes Spider-Man. It will be very obvious when this happens because of the undoubted element of badass appeal, and the fact that the wearer will most likely be fighting crime and/or swinging from building.
John: I'm wearing a Spider Costume! Look at my eight legs!
Passerby: You are a loser/freak.

Peter Parker: Oh no! A bank heist! I must put on my Spider Costume and stop it!
Passerby: You are undoubtedly badass.
