This is a set of FILA T-shirt and half pants. I bought it thinking it would be good for my child's pajamas, but they grew out of it without wearing it, so I'm selling it. The size is XL (18), roughly a little bigger than 160cm, about the size of an adult S. I've worn it once or twice. There are no noticeable stains. Please refrain from purchasing if you are very concerned about details. Thank you.
