Bobby pins; holding hair in place since the 1920s. Named after the “bobbed-cut”, women who rejected traditional roles chopped off their hair and adopted the bob cut as a sign of modernity.
The pins come in discreet colours and were meant to blend in and hide in the hair. I usually use silver ones, but this time I went for a black pack in the beauty supply store. Sliding a whole bunch of them around my face to keep my bob in place like a headband.
