The waist can be adjusted with the elastic, allowing for a perfect fit. There are adjustment buttons on both sides. It's larger than other size 100 items, so it can be worn for a longer period. In our house, it was often worn when the child was size 110. The thread on the button (left side) used to adjust the elastic is loose (see the last photo). Please reinforce it if necessary. It will be delivered as is. Please refrain from purchasing if you are particular about details or if you cannot accept even minor oversights, as this is a used item. Please excuse slight differences in color and folding wrinkles. Pant length...Full length
