How to wear vintage jewelry like these snowflake brooches? In the 1940s brooches were worn together as a set. In a Paris auction, I bought this lovely set of 2 small snowflake brooches. One is a little bigger than the other. Snowflakes were extremely popular after the war. Van Cleef & Arpels introduced them in 1946. Here you can see 2 advertisements of how to wear them: The lady with the snowflake brooches on her hat is from VCA and the other lady with a set of diamond clovers are from the House of Trifari.
