220 D 20 30 The 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 GUCCIs double G or Diors CD buckle are more popular. This one is the classic DIOR letter series. The 20 ultra-thin ones have saved so many big clothes. I really really really like the exquisite and very beautiful Dior belt.
