I think the fundamental problem here is that you want to generate a static
charge that is "safe" but "powerful enough to cling clothes to the
body...from a distance".  I don't think you can do the latter and still be
"safe" for anyone nearby.  At least, that is definitely the case in the
world of DC electricity, where a Van de Graaf generator would be of use --
it is possible that you could use something AC (such as a Telsa coil --
you'll need to read up on those) to get at some of the effects you might be
after, though not specifically clinging clothes or raising body hair from a
distance.

In any case, I'd suggest speaking to and working with someone locally who
knows a lot about high-voltage AC and DC electronics, who can talk to you
in detail about what you want to do, advise you how to make it happen
safely, and double-check your apparatus before you power it up for the
first time.  Electricity is no joke: even when you know what you are doing,
it's frighteningly easy to zap yourself (I speak from experience here) in
the low-voltage world, and venturing into the world of high voltage without
practical experience or professional help is like putting a cosmic "kick
me" sign on your back.  It only takes about 300-400 Joules of electrical
energy to stop the normal human heart, which is all too easy to muster at
the kilovolt potentials you're talking about.

I'm not familiar with Otis College, or the surrounding areas, but you
should be able to find a local physicist or electrical engineer, whether at
Otis or at a nearby college/university or a national laboratory, who can
help you set something up safely.  There are a lot of great demonstrations
you could adapt for your purposes, and I'm sure that someone would be happy
to help you get it all set up.

So, bottom line:  Get some help.  After that, good luck on your project!
