I remember looking at a high-school yearbook from the beehive hairdo era and remarking to the owner, Geez, you all really wanted to look just alike. I went to high school in a day and place where the girls grew their hair long and left it down, and in looking at that yearbook, all I could see was the beehives.
In fact, at a second look, of course the faces were quite distinguishable. No doubt they were more readily distinguishable then and there because varying hairdos did not distract one from the faces.
