Sz 6.5 Escada peep toe champagne silk

sz 6.5 Escadas. I'd describe the colour as champagne almost a rich brown. It has beautiful brown straps and gold detail. They've never been worn but tried on a few times. The gold has started to tarnish. Not sure if there is a way of polishing it up. you can wear them as is, does not take away from the shoe.
