Jumpsuits are one-piece suits. I guess the idea is that you can just jump right into them (this doesn't work very well, particularly if your suit is a little too small). You generally wear them over other clothing, particularly because they often have false pockets which are kinda nasty if you're not wearing anything else. Or else maybe that's sexy. Whatever.

You can find jumpsuits at places like Goodwill, they will be cheap. People might laugh at you at first, but be assured that you will be the life of the party if you wear the funky jumpsuit. Especially if it's red. Here is expert testimony, live from the noder par-tay that I am at:

Where did you get your jumpsuit? that's really fucking cool. I want one now... but I'm not sure that's my color. --(anonymous Lawg member who chooses to protect her identity so it does not ruin her editorial reputation.)
