Haha, or in my mind "age it up". Brooches should be saved for the Queen (Correction, it can be done right. But on coats 99% of the time looks elderly)
I don't know anyone my age who wears brooches, and I'm younger than Camilla and older than Catherine. I inherited a couple of beauties from my MIL, but I'll either have them broken down and reset, or wait until I'm a lot older.
