You might find these too expensive (you probably will actually) but I'll post them here anyway.
The thing is, it's better to save longer and spend more on a shoe that will fit you perfectly, than to spend less on something not as good.
Anyway: Andy Burke's shoes:

Sarah Juniper shoes: http://www.sarahjuniper.co.uk/
A girl on a costume community on livejournal actually went along with a pair of bridal shoes (but she was improvising on a different period) so that might be worth looking into.
I'm a boots type of girl myself so I'm afraid this is as much help as I can be, I hope you found it at least slightly helpful.
