There sure a lot of posts that claim if you dress "nice" you play better. I'd venture to say (though I may be wrong, if so I apologize) that the OP has said this at some point in the thread. Even if not, a LOT of people have.
Edit: I have actually gone thru the first 10 pages and he did not say anything of the sort. I assume now that he did not at any time in this thread. Sorry NM.
