As someone who sells vintage costume jewelry, I’m aware that some of the jewelry can look “granny-ish”. I tend to wear a lot of vintage necklaces and bracelets but not too many pins. They’re a little tricky sometimes to fit into an outfit without looking matronly.
My favorite was to wear a pin is to use it to anchor a cute scarf. I drape the scarf around my neck with one end in front and the other end over the shoulder. The photo above is a good example.
