I have a dress form that wasn't very "me". Not too long ago, Craftsy offered a class showing you how to customize your dress form to make it you much more like yourself.
i found the class was very helpful with making the changes and you end up with a better fitting dress form. My dress form now has the same measurements that I do. ( poor thing! ) I wish this class would have been available long ago, but am glad they have the class now. You might want to check out the class.
