Looking for general appearence information.

i know a few ppeople in the business and am just researching best appearence methods, when i bought my first house about 2 years ago, my inspector came w/ dreadlocks and gauged earrings, now i wasnt offened by such, because he was very presentable, pleasant, and knowledgable and did a great job, now in others eyes would this look as a bad thing and why personally?
