I purchased these at GU about two years ago. I've worn them outside 1 or 2 times, but haven't had much opportunity to wear them, so I'm selling them. The size is M. For reference, I usually wear shoes that are 23.5 cm. I couldn't select size M when listing, so I chose 23.5 cm. They are in good condition, but please note that I am a private seller, so please excuse any minor imperfections. These are gray ballet flats with a fuzzy texture and a cute ribbon design. - Color: Gray - Design: Ballet flat style - Material: Fabric (fuzzy material) - Decoration: With ribbon Thank you for looking.
