I apologize for the double post, but I just wanted to mention that I love the suggestions in this thread. Ismene mentioned a few different ballet/ballerina characters-- how about the White Swan and Black Swan from Swan Lake?
I also love Janilew's suggestion of a traditional barbershop singer character with striped suit and straw hat. I could work him into my Victorian world very nicely indeed!
I feel like the characters from Clue-- Colonel Mustard, Miss Scarlet, Professor Plum--could make nice figures, and could come with their various proposed murder weapons. Though this might be a bit too adult for Playmobil!
