Ian, why not do what I suggested earlier, a very simple, small circle
pin. Texture or plain to suit your fancy, you don’t need stones or
any super-structure like we’ve seen. It would look completely
dignified and gender-neutral. If you want something more casual when
not wearing a jacket, make it a clip-on rather than pin. Keep it
small and light. One silver, one gold - or a two tone of twisted
wire. Get dreaming.
