Vicars And Tarts Party Ideas In Belgium

Am moving to a former 18th century convent in a Belgian town south of Brussels. Place is is really gorgeous and would love to hold a special housewarming party in keeping with the style of the house.

In keeping with the `religious` theme, thought I`d throw a "Vicars and Tarts" party once house is finished being painted etc. This kind of party is best known in the UK whereby the guys come dressed as vicars (clergymen) and the girls dressed as `tarts` (ladies of ill-repute).

I plan on hiring a nun`s costume (but dressing sexy with a garter belt etc underneath) but has anynoe got any ideas as to decorations, food, drinks game ideas ???

I`m Canadian orginally but love this idea for a party (nothing `weird` will happen .... Just typically Brit party idea is all....anyone see Bridget Jones` Diary ?).

Thx for any ideas !
Kind rgards,
Donalda
