Well, Naomi the visiting ethnologist/anthropologist!
Fashion’s a funny thing. At least one regular here will tell you it’s an example of a socially contructed reality.
We all position ourselves in relation to our own perception of how society is. We all have different ideas of how society is, because we all see it from different windows.
Some people try to blend in, fit the formula, be unobtrusive. Maybe they define success as ticking all the right boxes: smart house, smart car, respectable spouse, two nice kids, decent pension arrangements, foreign holiday each year. Others blend in in different ways: Burberry check, lots of gold, bleach blonde permatanned girlfriend…
Others position themselves on the margins. Some “over conform”. They might be exceptionally respectable (very big smart house, very nice car, spouse is a JP, kids go to Oxbridge, etc.) or exceptionally main stream chav (hell of a lot of gold, totally pimped Subaru, etc.) or they might rebel, deliberately not conforming.
Whatever we decide about our appearance is influenced by what others wear, by the associations we have with that style of fashion. Those associations change with time, but they are nonetheless real. Jeans used to be workwear, then they became teen fashion, then they became high fashion, then they became retro… and so on.
I had my ear lobe pierced in about 1985/6. It was primarily because I wanted to wear an earring as part of my Morris costume, but partly an act of defiance. I was called in by the boss, instructed to remove it, I contacted the union, we had a debate, and I was allowed to keep the earring. That was worth something because I was the first male employee in my office to make the stand and win. At least 3 or 4 others had bottled out.
But that was ages ago. 20 years, and a single pierced lobe is now completely uncontroversial. I personally don’t like facial piercings, but I think a single extra piercing in the ear looks OK. It irritates the boss a bit, which is good, and it just reminds me that I may have to play the company game all day, but that I am a person, not a number. (My company thinks I’m UROI13 - yes, really.)
But Naomi, you wrote
<<none at all have any facial piercings, ear-rings excepted.>>
Why except earrings? You display your own view of normality there - a prejudice of sorts.
