The style of nursing cap has more to do with the nursing school you attended. In some places, NYC, Boston or Pittsburgh for example, one could tell by looking at the cap, what school the nurse attended. I wore my cap exactly twice. When I was given it at the end of first year, and when I was pinned at the end. It has one stripe, a ribbon of black velvet attached with hot glue! LOL It was an associate degree program, at it used to be a 3 year program run by the hospital until it was moved, lock stock and faculty to the community college.
Poke around on Pinterest and you'll see all manner of caps. you'll also see pins from many different nursing schools.
It's said the cap evolved from the nuns' habit and back in the day British nurses wore some wild caps!
Can't tell I majored in history the first go round! Nah!
