Listed as 100cm, but it's actually 115cm. I used this for three years, starting in 2000 when my child entered kindergarten. The gray fabric on the inside has some pilling. Since my child wasn't very active during bus rides to school, the outside condition is relatively good. My child was 100cm when entering kindergarten and 115cm when graduating. When entering kindergarten, the hem was long and would catch on the knees, so I folded it inward and sewed it. Some threads are coming out where the fabric caught. See images 10, 11, and 12. I wore it for over a year after undoing the hem, but the fabric is tightly woven and didn't seem to fray. Please refrain from purchasing if you are concerned. It was the perfect size when graduating. The elastic wasn't threaded around the navel area of the waist; I think it only went from the sides of the navel to the back. (I don't remember exactly.) Because it lacked a good fit and the waist would slide down, I sewed fabric onto the navel area so that elastic could be threaded all the way around. There are stains on the added fabric. The sides of the fabric are open, so you can replace the elastic. It was also convenient because you could tell the front and back of the pants. Please understand that there may be oversights. Total length is about 35cm. The color may be slightly different. Please refrain from negotiating the price.
