You mean aside from borrowing my waistcoat? You could go with a marcella vest, and high wing collar, or completely the other way, with a cummerbund, and turn down. Cummerbunds were new, and very fashionable, in the 20's. You could wear black and white spectators, if you want to be tongue in cheek - I think that depends how "gala" it is, vs. how "costume."
Some Art Deco links and/or studs would help. A Homburg, of course! Fat lapels, if you have a DJ with that feature. White DJ's arrived in the 30's, so avoid being one of the people who will, inevitably, confuse Casablanca with the 20's. It also doesn't go with the wing collar shirt you plan to wear.
Care to fly me out, and take me as your guest? Failing that, a lady in a flapper dress, something like the white one my wife is sporting in one of my recent photos. Wear such a woman on your arm, and your own efforts will be delightfully overlooked.
