Haha, that's true for sure. Back when I was young and a freelancer I went to a networking group with mostly non-technical people where the dress code called for a suit. I wore bright red skate shoes with my suit.

I came across as "that young technical wizard" before I even opened my mouth. You should totally use those stereotypes to your advantage when you can.

I thought about adding my thoughts about not overdressing when you need to come across as technically proficient because of the stereotype but thought that would have muddled my point.
