A lot of those masks people in China wear they refer to as privacy masks (though this seems more an auxiliary usage -- especially in HK -- where the primary use is for filtering air). So I'd say there is evidence of such styles already becoming fashionable.

In Japan the stereotypical get-up a bank robber would wear isn't a ski mask but a medical mask with sunglasses and baseball cap.
