Used twice for a short period as the child didn't like wearing it. Hand-washed and stored at home. As shown in the last photo, the seam at the armpit appears to be loose, but it was like this from the time of purchase. There is no tag on the clothes, and I can't find any purchase history, so I don't know the size. It was a little big on a child who usually wears size 90, so it's probably size 90. A child who currently wears size 100 can also wear it, and it fits perfectly. There is some slight fuzzing and pilling. Please refrain from purchasing if you are concerned about this. ※Material: Cotton/Polyester
