I pay particular attention to the people who dress casually around me. Let’s say you come to our meeting wearing a T-shirt and some jeans. That tells me you’re comfortable. Not necessarily a bad thing. If I sense you’re going to do great work, then that comfort level is appropriate. If you don’t transmit a competent air, however, then I’ll view it as a liability. It suggests you’re not taking the situation seriously enough. You’d be surprised how many people do that.
