It would be a mistake to make a splash of the quiet trickle of societal conversion, but it can be a source of hope to note this sort of thing:

A handful of Roman Catholic convents are contradicting the decades-long slide in the number of women choosing to devote their lives to the sisterhood. And at least two of them are doing it by sticking to tradition, including the wearing of habits. …
Sisters at St. Cecilia’s and other thriving U.S. orders typically are younger, which makes them closer in age to potential newcomers. These orders also emphasize traditional practices, like wearing long, flowing black-and-white habits, and educating students.

There’s no denying that religious life has become less mainstream of an option, over the past century, but it’s a mistake for religious organizations to chase members into the brambles of a decaying culture. Those who wish truly to commit will do so, and maintaining the markers of difference will be, for them, an attraction, not a deterrent.
A plain statement of purpose and a resolute following of tradition create a powerful beacon, and it’s left to those of us who believe to stop going along with the pop culture assessment that there’s something peculiar about following it.
