I always wear a bra in public, and sometimes at home too, but I'll be the first to admit that once in awhile it starts riding up under my girls and it's always in public when it happens. Then I want to scream, but truthfully, I enjoy it most of the time. One thing that bugged me and a lot of other women on a site I no longer visit is that a moderator said in no uncertain terms that if you didn't take it off immediately after you got home you were essentially a crossdresser, which I found amusingly offensive.
