It is a truism of the history of dress that decade-defining looks generally don’t congeal until quite late in the period they eventually come to represent. The miniskirts and Crayola colors of the 1960s, the power shoulders of the ’80s, the minimalism of the ’90s — all reached critical mass well into the midpoint of those eras, when whatever had been bubbling up in wardrobes and on sidewalks found its reflection in the wider world.

Well, we have finally reached that stage in the 2010s. The tectonic plates of fashion have shifted. Look around. What do you see?

Look to the runway: During the recent round of fashion shows, suits — and sleeves and long skirts — dominated. Look to the street, and the stores.
