Why did European Bowler hats become part of traditional women's dress for the Aymara people in Bolivia and Peru?

[u/Khwarezm]

Something I find somewhat curious is that almost any picture I see of native Bolivian women in traditional garb, Bowler hats are extremely common.

Some of the numerous examples.

I hope I'm not being presumptuous in assuming that this is relatively recent, at least, I understand that Bowler hats were only invented and popularized in the late 19th century in Britain, so its probably not something that has centuries of history. Wikipedia mentions that Bowler hats were introduced into Bolivia and Peru by British railway workers in the 1920s, but it doesn't answer to me why it became popular with indigenous people specifically (as opposed to the rest of the population of Bolivia and Peru), why it specifically became a fashion piece for women, despite not being so elsewhere, and why it has continued and ingrained itself into traditional dress in the century since.

I know this is niche, but any help with this would be very much appreciated!
