One very popular accessory in the 50's and 60's was the circle pin. They were all designed so differently but were worn on a sweater or jacket. Some people think they had special meaning like whether one was a virgin or in a relationship. Personally after doing some research I believe that they were just popular kind of like the plastic "sex braclets" my generation wore. Every girl had them all over her arm but no one I knew was even sexually active (we were in middle school). They were just cheap and colorful and fun to wear. You can still find these at some vintage stores. Anyone have a collection of these pins?
