The more traditional style Molly teams have a single "Molly" who is dressed as a female. Mepal certainly do, and Old Glory Have a "Lord and Lady" - the Lady is like a "Molly" and the "Lord" is dressed a bit smarter than the other men with a black top hat instead of the usual brown Trilby.

I think skirts are mandatory for all dancers and musicians in Gog Magog, and certainly an acceptable option for the men in Pig Dyke.

The presence of one or two special characters dressed differently (and sometimes a man dressed as a woman) isn't limited to Molly dancing, of course. Many Cotswold Morris teams have a fool and a hobby horse or other animal, rapper sword teams have a "Tommy" and/or "Betty".
