BHLDN Bettye Muller polka dot d’orsays heels

I phone ordered these shoes from the Texas store of BHLDN (Anthropologie’s sister store for bridal). I was desperate to have them and paid $350 USD just to get them. I thought I could make a 39.5 work, but I am a solid size 40 (10) and unfortunately these are not a good fit on me. These shoes are made from a vintage silk polka dot and feature a metallic bow. They are elegant and I wish they could work for me, but would best fit a true 9.5. There are dark marks on soles from walking on tile.
