Yes, it does seem that this could be done better using the Cloth Room. Cloth simulations aren't too bad, as far resources go. At least when compared to gazillions of built-in morphs.

Has anyone tried to clothify The Dress? Does it work? I've tried clothifying the Morphing Fantasy Dress, and some people have reported success, but for me it takes forever. Clothing that's specifically designed to be dynamic is much, much faster.
