Roger Vivier style D'Orsay ballet flats Yellow Gold Crystal Strasse Buckle

Golden yellow satin d'orsay style ballet flats with large crystal embellished buckle. I bought these on eBay and suspect they're NOT authentic Roger Vivier though they look it. I do not have a dust bag or box for these though they have been barely used as you can see in photos - just a couple of tiny scuffs at toes. Love this mustard gold colour! Price is firm as I paid more in USD for these. They are marked a 40 but run smaller so please compare measurements below to a pair of your own shoes to determine if they will work for you. Inside length 10" Inside width 3.25"
