I'm going to a Flapper theme party on Saturday night and I'm already feeling jealous of the great costumes other people will, I'm sure, be wearing! But it's fun to browse online to pretend that I'm about to buy vintage costumes.
Or there is the Halloween costume angle! 
But I will wear a lovely dress from my wardrobe, a Banana Republic collection dress in ivory silk that falls in wide pleats to above the knee, and see if I can add a sash of some kind!
