What to wear: You'll need some friends to pull off this look, since each of the Harmons on their own isn't very recognisable. For Vivien, you'll need a long, wavy red wig, a modest dress, and a little white dog to carry. Ben is easy: just throw on some khakis, a shirt, and a blazer, and don't forget the fedora. Violet needs a baggy floral dress and a mustard cardigan.
How to act: If you're Vivien, be cautiously optimistic. For Ben, get increasingly irritable and suspicious throughout the night, and if you're Violet, you're a ghost, so be forlorn.
