2015. I've been getting more and more into vintage dance. Mostly Regency and Lindy Hop, but my favorite I think is Ragtime. Ragtime is super easy and funny, and the music is goofy and upbeat.
This photo is from a Ragtime Tea series hosted in by Commonwealth Vintage Dancers in 2015. People really have the outfits. I'm getting there. I have a decent Fezziwig's (Dickens era) gown and just ordered a Regency one.
