I don't know how it is in other cities but Seattle is casual to the point of almost slovenly, filled with unimaginative Tech Bros that can't dress themselves........At least a lot of the women still dress nice.
Funny, that was the second time in one day I saw the term "Tech Bros."
Last night at my wife's birthday dinner I looked at my oldest daughter's significant other (age 36, involved in the IT/Tech industry) and it hit me that he and I were dressed nearly identically. Sneaks, jeans (I dressed up in cords for the dinner) sweater over T-shirt. (I had a much nicer sweater.)
I think I'm a Tech Bro. Considering my career working with classroom technology and design over the past decade, I suppose that works.
