to be honest vintage is always in. as far as the gold i would advise you to keep it simple, you don’t want to over do it and take the light off of you. remember its your day to have everyone looking at you and not what you bridesmaids are wearing around their neck. but to answer your question yes it will blend nicely as long as they only choose to go with other simple pieces. so no matter what their choice on shoes they still can have a classic look.

Since jewelry is usually worn on the neck or ears, vintage gold jewelry would be suitable no matter what the shoes look like. It might be a good idea for the shoes to be unobtrusive, so the jewelry will be notices, not the shoes.
