Decency brooch - fly
Length 1.5 cm.
At the end of the 1800s, social life between men and women was highly regulated and only when you got married was the interaction more free. Young men and women could therefore not walk hand in hand or the like, not even when the man was courting and eventually wanted to marry, physical contact was a possibility. But every gentleman then waves a fly away from his beloved's shoulder or chest and from this arose the fashion for brooches shaped like insects.
This fly can also be screwed onto clothing.
