Just to give you an idea, here's a render of mine that came out particularly well (except for a few AO artifacts, it seems).  I don't use dynamic clothes often, but I do occasionally experiment, and I'm rarely disappointed.  My only beef with this particular item is that the straps seem to float a bit too high above the shoulders rather than resting directly on them.  Those folds on the top curving across and below the breasts are the best part, I think!  You just can't do that with conforming clothing.
