All of these shoes are quite classic and if you can't hunt down the vintage pair, a quick pop over to Endless.com will probably result in a vintage inspired pair. I'm not quite sure about gloves, I've never cared much for them, although I still think they are quite appropriate for the opera. I do however, ADORE the white "double nylon" pair for $1.09 (save .40!) those are just so cute!
