“what was wrong with leggings”
From a technical standpoint (as long as the skirt keeps the knees are covered), nothing. Its no more attention grabbing than tights.
But from a statement standpoint, it screams at the top of its lungs. Kinda like the way a hemline can be long, and it can be so long that it drags on the pavement. The message is intentional, and comes thru loud and clear.
Not pointing fingers at anyone; just sayin’…(v’hamavin, yovin)
