This is a DeNA BAYSTARS kids' uniform. I purchased it officially, but I bought it a few years ago, so the design seems to have changed now. The size is 100. I wore it three times to watch games. Although it has been worn only a few times, there is a faint, small stain on the bottom, probably from being at the stadium. Please refrain from purchasing if you are sensitive to used items or home storage. I will compress it for shipping, so please understand and purchase it. ^_^
