I'm in my 40s now, and I would say in HS and college, most had landing strips or narrowly trimmed bikini lines... not sure of a better way to describe it, but maybe a finger width of hair on the sides.
In my later single years, I didn't come across anything but shaved. My age group of women was always meticulous with their shaving routine, and the younger ones had no problem with a fair amount of stubble at times. I always took it as a sign that they had been thinking/planning on something happening when they were perfectly shaved.
