I have a dress form, her name is Nancy, because that is the only time I have ever used it. I made a wedding gown for Nancy and sized it to her. It's still sized to her. I, personally, don't think a dress form is much help for pants. I keep trying them on until I get them to fit the way I want them. Yes, sometimes I'm sewing in my undies. I know, TMI, sorry. Glad I didn't spend the money for one, mine was given to me. These days she just holds my tape measure, and some dust.hehe Good luck, pants aren't always easy to fit.
