The 220 Dior womens belt has a width of 20. This one has been available for a long time. I rarely see anyone using it. I feel that the Yupoo Gucci double G or Dior CD buckle are more popular. This one is the classic DIOR letter series and is 20 super. Its so thin that it saves a lot of big clothes. I really really like the exquisite and very beautiful Dior belt.
