Janet, I agree with buddy -- Uncle Schmuck needs a curfew.
Old Navy has some nice comfortable loungewear. I susbcribe to their e-mail newsletter, and they send new sale offers at least once a week. Between the sale section on the website and the discount coupons they e-mail to me, I can often save 50 to 60% or even more. And their return process is good, if you get something that doesn't fit. They send all the shipping labels and don't charge anything.

I also included a link for Penningtons. It's a Canadian plus-size chain, but they also ship to the U.S. I'm not sure of their price range, but I have a few friends who shop there and they always look great. And I think they go up to a size 6X.
