It has always been this way - and everywhere.
And it will always be.
Race has nothing to do with it, a s race per se, as a distinguishing matter - of course, if you are a one white dude/dudette in Namibia, you are going to be treated differently.
Clothes and appearance have always been and will always be a part of belonging to a caste. Some defy it but that is also a statement ( like the bum in the lobby to be a client etc).
Some appearances are culturally connected - you will have plenty of older women in South Florida ( and generally in the US) with long uneven strings of grey hair on their shoulders still thinking they are sirens from the 60s, but it is almost impossible to meet their peers with such an unruly hair in France or Germany - women there know and remember that as woman ages long grey hair flowing around as it used to when they were 17 does not make them look pretty and just underline their age.
Same is with makeup. Latin girls and women use makeup in a way Russian ones do

French do it differently than Germans and Italians in a different manner than Americans in NYC.
men differ in their styles as well. Young straight Italian might be considered gay in NYC or South Beach
