I've been thinking about this for a few weeks. Specifically I'm talking about the beards like the following
Do you need a certain facial structure to pull this beard off? Also, the mustache twirl isn't necessary but preferable. Lastly, I'm in Finance so I'm wondering if this will be considered unprofessional?
I don't even think it's this. Of course everyone's hair is different but facial hair is generally thick and course, like pubes.
