Tory Burch reva flats

Tory Burch reva flats in a deep navy. I purchased these on another platform, the seller listed them as a women’s size 6 however I believe they’re a youth size 3? Really not sure, I have TB flats in sizes 6 and 5.5 and they fit me fine, these are far too snug for me so listing as a size 5. There is some discoloration to them, the previous seller said she used shoe polish on them. Otherwise these are in great condition!
