Adding dForce to an object is really simple - there are plenty of tutorials on it. Essentially, all you have to do is add a modifier, and possibly tweak a few settings if you're trying to achieve cloth that's heavier or stretchier or stiffer or whatever than the default.
The problem is that not every piece of clothing works well. (Or at all.) If the mesh self-intersects, the simulation will blow up. If the creator didn't actually fasten parts togther (just parented them and positioned them) they'll fall off. If the mesh is too coarse, you get "jaggies."
But there are now a TON of dForce-enabled clothing items "out there" now, so getting one that's already dForce-enabled (and will simulate correctly) is not difficult. (They all have "dForce" in the name.) And a fair number of pieces that weren't designed for dForce will work with it. There's a thread in the Daz forums where people were listing items that weren't, but would would work.
The main nuisance is that it can take a while for the dForce simulation to run. But I've had some reasonable success with it for certain "draping" problems - the one you mentioned falls perfectly into the domain it was designed to solve.
