I have 2 pairs of classic pumps here for your Lady.
The gold are brand new and are size 36. ] shipped
The black pumps are size 37 1/2, and have been worn once. SOLD shipped
I can't believe how much these go for checking on ebay, my wife wears them once or never and they end up in the bottom of her closet.
I forget how much I paid for them. I paid for them because "I am so good at finding things on sale", I also end up paying for them. They were over $400 each.
