This is a Mikihouse summer hoodie, size 100. It's a rash guard, and I bought it at a department store. I had trouble finding this kind of product in gauze material, so it was very useful in the summer. (Because it's gauze material) it may show some signs of wear, but I think it will still be useful. I've added a photo to the fourth image because the arms are a little dirty. This is a used children's item, so please understand. Thank you! ^ ^ Note: I don't have a smartphone, so I may not be able to reply immediately (＞＜)
