In my own observations and experiences, doing things based around making sure people see you how you want them to see you is BS. When you do that there's only one group of people that pays attention. High school students. The rest of the world is busy worry about the real world where looks just don't matter as much as they used to. When I got my job I had long hair and an eyebrow ring. I bailed on the ring and my hair is even longer. Do they care? I'm sure they'd like me to cut my hair, but so long as I keep the quality of my work up I don't think anything's going to really go wrong.
