I headcannon that Ciel sometimes accidentally takes the role of the woman (?) while dancing since he's used to dance with Sebastian/Druitt. Elizabeth doesn't realize it when it happens because she's used to taking the role of the man (due to being taller than most of them) when she practices with her friends. They have made it into the front page of the newspapers thanks to their "cross-dancing"
(I don't know Victorian era dancing terms but I don't think most of us do. Besides, language is languaging as long as we understand each other.)
