I hadn’t considered using the male voice but I see the point, if they already know you are a cross dresser why struggle with the voice. I will still practice “the voice ” and which voice is used will be a case by case decision.
As for outfit and makeup I think it will remain more sedate. Generally the crowd will be a mix of straight and rainbow, old and young so it can’t get too campy. But if they want it over the top I will have to take my game up a notch.
