I hate the way most clothing feels on my skin - I typically wear a base layer (of something I do like the feel of) underneath my work clothes when I have to be out in public. Another tip is to have business-wear tailored to fit your body properly. It really helps keep things from riding up/down and sliding around or bunching up and causing even more irritation.
I also tend to "steal" ideas for looks from people. I have terrible fashion sense, but I know what looks good on other people, so I copy them.
