I totally 100% reject your notion of 'the clothes makes the man'. that was from a bygone era and no longer applies.
Clearly you'd be able to safely know things about me if I had that tattoo.
Sport a few tattoos and it won't do yourself any favours trying to get a job in a professional company as an engineer. Same with men dolling themselves up with earrings. Lets' face it, you won't find the CEO of a major corporation with tatts around his neck and over their skinhead with a couple of dainty earrings dangling from his ear lobes. One company I worked with had a brilliant IT bloke - the best of the best - who had multicoloured hair (he was not a natural greenhead). He had a great attitude, aptitude and ability. He went for a job as an IT manager where he would have excelled, but didn't get it because he did not fit in the corporate image. The bloke who got the job proved to be a complete IT moron - full of
and little skill. Lets' face it, people judge by appearance.
In Japan, in general you are not allowed to enter a public pool is you have got tatts. That includes women. If a shop keeper sees a tattoo on you, they will often put up their hands symbolising "I refuse to serve you. Now, get out." The reason is tattoos are associated with undesirables like the Yakuza.
So if you don't look the part and conform, you do limit your options.
