One thing that was very popular at the time for wedding shoes were Daniel Green boudoir slippers. Usually of satin with peep toes and cling backs, but also closed backs, with ruffles of satin on them. They show up on eBay every once in a while. However, the platform style is fine with the wedding dress you have because it looks like its post war and the platform was really not popular until post war, expecially in England. In fact I don't think there were any platform soles in England until 1947ish.
