Searching for Josh Costume

I’m searching for Josh costume for their party on Wednesday. Every year they have this costume party held on last week of October. For two years he used his Robin costume but this year I want another character or another kind of costume. Just this morning Josh was telling me if he could wear scary costume. I told him it will not fit him and I don’t want him to look like a zombie or Frankenstein even on costume only. We were both looking and searching online for possible costume and I pointed out to him that it’s not necessarily a scary Halloween clothes or look but anything that will look like a costume. After one hour of explanation he succumbed and we settled for Spiderman. Of course he loves Spiderman it’s one of his favorites.
