I mean, we've had a similar transition recently, with similar holdouts. See hats; they were basically essential wear in the west for men, from working class up, at the start of the 20th century; by the end, hats as male formal-wear were largely seen as pretty eccentric.

In the case of wigs, there were holdouts; barristers and judges in the former British empire have in many cases only really started abandoning them over the last two decades.
