Size: M size I usually wear 23-23.5cm, so I've listed it as 23.5cm. Heel: Approximately 10cm I bought these several years ago and wore them a few times, but I'm selling them because the heels are too high for me to wear now. The frill part is made of suede fabric. There are no noticeable stains, but there is some wear and tear, and the strap on the right shoe has a slight bend (see photo 3), but it doesn't affect wear. Please refrain from purchasing if you are looking for perfection or are overly sensitive to imperfections.
