I have done some animations with dynamic clothing, taking off a sleeveless dress, bra and panties and putting on a dress as well as getting out of bed under a blanket.  There are some things that need improving, especially putting on a dress.  What it took is a lot of temporary specially made props, a lot of experimentation and much patience.  This was done with Poser 5 and I think it would be much easier with Poser 7.
