There are a lot of folks who don't have Poser 5, and don't intend to get it. Since you can pull the dress in as an object and create dynamic cloth with it, I think it was a good move on Daz's part to create it for Poser 4. I have both, but like I said there are some who don't, and I hope NOT to see a trend of all dynamic clothing for that reason. Just my thoughts. 8^) Marque
