A few years back(?) in the US you could pick up a halloween costume for the kids off the rack at the convenience store. The costume comprised of a plastic mask and a printed plastic bag to wear over the body. Halloween is a real big deal in the US with everybody getting involved. I guess these were perfect for a busy lifestyle/lack of creativity types who want to be involved. I love the look of these and you can see where streetwear brands might have got some of their influences from. Check the Jaws, Flintstones, Cookie Monster, Planet of the Apes, the list goes on.
Going out dressed as a Asteroid or flipper is always going to be fun although the Village People one would be an interesting call in the school I went to.
