I bought this in Guam! The size is 0. I usually wear a size 61cm at Uniqlo, and this is about the same size. The fabric is sturdy, so it's not worn out. I bought two, but I can't wear them anymore because I'm pregnant, so I'm selling them. I have another one of the same pants, and I loved wearing them at the office because they're easy to care for (no ironing needed) and look neat! Never been used. The original price was over 10,000 yen!
