As a mechanical engineer in the Seattle area, I see one extreme to the other. I shave my head by choice, not for lack of hair, and have worn the same large goatee for the last 27 years. I'll wear a suit and tie, when necessary, to increase my level of visual professionalism with certain new clients and to cover a large amount of visible ink. Most days I'm in shorts, a t-shirt, and, according to my lovely wife, look like I've just strolled out of San Quentin, depending on my facial expression. I even made an informal request regarding their opinion on me getting my throat done (3 inch Roman numerals for my daughter's birth date). All I was asked was how much time off I'd need and how bad it'd hurt. Different strokes for different folks, but not exactly the norm in much of the country.
