All them wild boys I worked with in Texas weren’t cowboys either, (well, some were) but they wore the boots. Florida too. It pays tribute to a long and storied history.
This seems like a concept from the past.
I don’t even see American kids dressing up as cowboys any more.
In Texas.
As to adults…not so much any more, at least not where I live.
I am all for “culture appropriation” and people being whoever the hell they wish to be, but it is kind of funny going to a country concert in the Northeast.
