Authentic Garavani Women's Rockstud Leather Pumps

I don’t have any proof of documentation these are real as I bought them from a resale store over 6 years ago. They are in good used condition except the heels have discoloration that was already there when I bought them. It’s a yellow discoloration. I personally only wore them twice which is why I’m selling! The heel is about 2.5”. All studs in place. These go for $1100 new, I purchased for about $400 and would like to sell for $150 or best offer. Please let me know if you have any questions! They are a size 36 which is about a 6 in US sizing.
