NWOT Gianvito Rossi mules

Gianvito Rossi mules. Tiffany blue suede. Gorgeous shoe. Literally just got them and they are too small. These are a 39.5. I am an 8.5 and these run very small and narrow. Would probably be better for a 7 or 7.5. Comes with dust bag. Heel height 3.8 inches. NO LOWBALL OFFERS. These shoes are priced well below retail and have not been worn.
