Dear D.C., I don't care what you do so much as why you do it. Your professional title is not a substitute for a personality.
Never been a fan of gaudy, flashy, tacky things and can't stand the overindulgent/self-important personalities that usually accompany them. True, nice things tend to be expensive, but all things expensive are not nice solely because they cost a lot. Good design and pleasing aesthetics are not simply functions of cost - rules to live and die by.
Mostly a T-shirt and jeans guy, but I clean up well in a two button suit or a blazer on occasion - just don't expect rhinestones or animal skeletons to be on it. (Seriously, why is that still going on?)
