My son is currently wearing size 100 and can still wear it. He has a slim and small build. He will be starting kindergarten this year and will be graduating from Anpanman, so I am listing this. He loved it and wore it often. It shows signs of wear, but I don't see any noticeable stains or tears. I feel it would be a waste to throw it away, so I hope someone can make use of it. It was easy to put on him and for him to put on himself, as it fastens with snaps on the shoulders and sides.
