nurses' caps

Not so much now, but nurses used to wear curious caps, usually of starched cotton fabric, folded and sewn into varied shapes. I was told each nursing school had its own cap design and insignia. One could tell where a nurse received her schooling by the winged or crown-like or pleated object perched and pinned onto her hair.  (I say 'her' - I never saw a man wearing one of these caps although many men now are nurses.)
