I have no experience with the way children are raised in asia and am horrified that this phenomenon is not constrained to one particular region
But the western world has been trending down in culture sadly... I was a teen in 2005 and it was grim even then. Everyone wanted to be black for some reason.
For clothes, despite having preppy parents I never adopted it until now. Pinterest is suprisingly good and white european women in their 20s and 30s have not adopted the jeans & hoodie gamer fashion I was so trapped in as a man.
But it has to be discovered and there is a hurdle there. The codes are oxford shirts, pleated trousers/trousers, coats, jackets.
