I remember reading about this awhile ago. Now that it summertime I wouldn't mind wearing a dress. HOWEVER I remember when I wore a dress on vacation a few years ago my thighs were rubbing some kind of fierce.
I saw this article on a blog about. Chub rub protectants.

I also seem to remember someone saying they wore some sort of shorts which isn't a bad idea. I think they wore boxer shorts.
If anyone wears something under their dress to stop thigh rubbing please share.
