Do you have a Kohl's near you? I live in NE Illinois and they are just starting to put the summery stuff out and I saw some dresses that looked like they might be cotton, although that is a fooler these days.
I've always had good luck with catalog ordering but I've put on a few pounds so I'm not quite the size 10 I think I am so now I don't do catalogs! I love shopping but this business of having to put stuff on bugs me! Good luck with your shopping!
