I keep telling people. your fashion stays mostly the same. (excluding flash in the pan outliers, like tall tees or extra baggy pants)
Our parents and Grandparents dress they way they did at 40 because that's how they were dressing when they were 20.
Grandpa was rocking a suit with suspenders and the hat, when he was a teenager. He kept rocking that shyt when he was 80 and so we associated it with 80 year olds. But we aren't suddenly going to start rocking suspenders just because we hit a landmark age.
nikkas born in 85 is gonna be 80 wearing jays and sweats because that's how we always dress.
