I saw some pics (clothed!) of some college students doing that once. Going to her classes and all with her boytoy as a bra. At least, that's what they claimed. I doubt the teachers would have allowed it during class. I mean, how do you train a college boy to keep his hands there, but hold still and stop distracting you? And distracting everyone around you, too!
As for the plastic molded kind, there is, of course, a website for that. Once you dig through the photogalleries and porn sites, it seems there are multiple companies out there making them.

And some costume stores are having trouble keeping them in stock

What I don't see is a do-it-yourself kit to make your own modeled on your favorite pair of hands. I mean, that's the best part, right? Not
just that they're hands, but
whose hands they are. They don't look all that complicated to make. It's just the hot plastics that are a problem.
No such problems on RK1/2 though. This is so going in my idea list for this Halloween.
[edit]Ooh! Makes great spy gear, too! Just have to model the fingerprints on someone with security access. And drawings of your boobs won't be much use to the police sketch artists.[/edit]
