See, this is cultural. And I thought the japanese made DAMN SURE no tattoos would show in a buisness suit because those kinds of tats were so associated with the yakuza.
But anyway, within banking, corporate culture, crazy hair, outlandish make-up, or extremem dress are indicators of "hey, look at me, I'm a rebel!!" and they can make a judgement about whether or not that is the type of person they want to deal with.
For a on set armorer that as to both enforce strict rules and be METICULOUS with lethal hardware, I want this guy
doing that job 1000000000000000% more than some purple haired goth chick, even if she has a strong family pedigree. She may have had the knowledge, but she clearly lacked the maturity, on-set presence, and discipline to enforce safety rules and a woman paid for it with her life. Her style of dress/appearance belied her poor capability for the job, it just is what it is. Not sure I would want my armorer looking like they just walked off the set of a gangland biker flick either. Professional appearance is the thing I'm looking for after vetting their credentials.
