I'm selling this item as size 110, but the tag has been cut off, so the exact size isn't clear. I have a small 6-year-old son (height 107cm, weight 17kg) at home. Because he's slender, the top is a little loose on him. The bottoms fit perfectly because I adjust the size with the shoulder straps. They can be made a little shorter or longer. I've taken photos with a measuring tape, so I hope they're helpful... I hand-wash each item before listing it. There are no particularly noticeable stains, but there is some peeling on the reflective triangle on the back. Thank you for your consideration.
