I have chosen the 1930s for a rather obvious reason. However, I am aware that the 1930s is not the most well known decade so I have done some research to help you fit into the period.

The idea is not fully formed yet but I am thinking of an afternoon/evening party, start around 15-17h and just go on as long as we want. I will serve cocktails and different types os sweet and saulty fingerfood (vegetarian and not) but no dinner. If you need more you can bring something to BBQ or similar.
You can bring a guest (boyfriend/girlfriend, husband/wife or best/special friend)
