Quote - the reason i see to not parent a cloth is when there are 2 layers.  i have never seen a cloth collide with a parented cloth, so i never parent either of them.  (i usually run 2 layers)
but if i was doing just one cloth i see no reason to not parent it...then you can move the figure around in the scene after the simulattion (just in terms of body, not specific body parts) and not lose the garment or it's simulation

 

good thought... I have run very few cloth sims where one cloth overlaps another layer of clothing, though I don't recall any problems with the few I've done even if both cloth props are parented.  I'll have to experiment more though, so thanks for the heads up.

BTW, you aren't limited to the BODY to move the figure after running the cloth sim(s).  You can move the hip too, say, if you have a dress parented to the hip.. or as a general matter in most cases you could move any part "upstream" of the body part to which the cloth prop is parented (barring moves which compromise collision results with other relevant body parts or which change the shape of relevant body part meshes, such as raising a collar).
