Everyone is making judgements, are you wearing black, are you wearing a suit, are you wearing fashionable clothing, etc.
My opinion/observation is that the more attention that is paid to your clothing, the more your engineering/code quality suffers. It like the IQ test: wearing suits impresses people who think highly of people wearing suits. Maybe it's better to impress people who think highly of quality work.
edit: It's foolishness to dress finely to make people think you're awesome. You're not more of a professional because you wear a tie and suit. You're just a guy in funny-looking clothing who looks like important people. If you want to be professional, do the job well, do it kindly, do it so it can be used for its intended purpose for a long time, do it with respect for other people. Dressing nice has so very little to do with professionalism.
