Two anecdotes from working in one particular office;
I more a suit 4 days a week, and odd jacket & trousers on friday. Nobody else wears a suit (I was once told I looked smarter on a Friday than my co-workers did Mon-Thur), including my boss most of the time. Over time, when people entered the Department needing us for something, they came to gravitate to me. Not so bad, it meant I controlled the workflow more than my technical remit allowed and everything ran like clockwork.
Until one day when the Chair of the Board comes looking for something (explanation: this is a technical office - IT & systems). My boss is (for once) on the main floor of the department rather than ensconced in his office, and notices as the Chair enters... and walks right past the boss in his cheap polycotton shirt and no tie and up to me to get his problem solved. Which I did, and he went away happy - whereupon my boss asked why he'd sought me out.
I just replied "I'm wearing a suit". Next week, so was my boss.
Similarly, I was talking to one of the other team leaders and she asked why I dressed so well. I pointed out that people naturally gravitate to whoever matches their preconception of the person they feel they should be dealing with. Dress in a suit, and you'll end up dealing with people who think they need to be talking to someone in a suit... and more importantly, people who don't think they should be bothering someone in a suit won't bother you.
"People," I said "Make judgements based upon how you are dressed. Clothes tell you things about the people who are wearing them"
"What about Jim?" she asked, indicating one of the systems guys, who was waiting nearby "What does how Jim dresses tell you about Jim?"
"Mostly, what Jim wears tells me that Jim doesn't own an iron"
*cue the laughter from most of the systems team, and a rueful admission from Jim that he didn't*
