I was at an event called West Coast Ragtime Festival this weekend. I think it's been about 25 years I've been on their bill of performers, most of whom are pianists. These range from youth performers to players in their 80s. I don't know if any of our British members would remember Neville Dickey who did some playing for the BBC and could be heard frequently on the radio when I was a kid. I thought he was 85 but someone told me 88. He's still an amazing player and I'm lucky enough to get to play duets with him.
It's a dress-up kind of scene and some folks wear full-on Victorian through Edwardian attire. Here's something I put together. I was on the fence about adding the hat but I did end up wearing it.
Vintage Royal Stetson, MF cravat, Lofgren shirt, FW jacket, AtLast pants, Paraboot.
