Vintage Lisner Baby Blue Enamel brooch/pin

This lovely pin really makes a dark color top/sweater/blouse or jacket pops. I always wore it with a black suit, dress and or turtleneck. Once again from Circa 1950's- 60's era. Please note that one of the rhinestone is missing on one of the stems....I just notice it using my large magnifying glass. I would say a man could get away wearing this with a suit and nice baby blue shirt....I think flower pins or abstract pins are best for men....
