Thanks for all the e-mails and the photo. Nice costume. Still not clear about Rain dancers and tornado dancers having limited experience as it were.
Yes Castillon would without doubt have worn an opera cloak. He was a man about town, a boulevardier, a dandy and he had the time and the money. I don't thimk he moved in the very highest circles of French society of that time but I think he moved between the respectable or outwardly respectable bourgeoisie, the demi-monde and bohemia with ease, between nouveaux riche, adventurers, artistes, writers, speculative thinkers and artists.
