I use dynamic clothes as little as possible, because the cloth room simulator is flaky and fragile. For clothes that really aren't going to move a lot through the simulation, I'd much rather use conforming clothes. I use the Tailor a lot, and it works well for me. It's not perfect and, as svdl noted, sometimes it really makes the clothes look ugly. The more morphs, and the more extreme the morphs, the more likely you are to get clothing that may cover your model, but in a way that defies physics and good fashion sense. If you're going to do animations a lot, Clothes Converter or Wardrobe Wizard might be a good investment. You could also try using dynamic cloth in the cloth room just to shape the clothes, and then turn the dynamic cloth into conforming cloth. Start your model out with no morphs, give the model full morphs at frame 15 or 20 or something, turn the stretch, shear, and cloth density down a little bit, and then run the simulation. When the simulation is done, save your newly deformed clothing prop and then go convert it to conforming.
