Non-smoker, no pets, no name tags. There are stains like the ones on the left side of the fifth item and the seventh item. I don't know the hat size, but the smaller one was worn by a 3-year-old. There's also a hat one size larger, so for siblings. The sunflower hat was free size. The 120 size pants in the sixth photo are sarouel pants. A set of various designed kids' clothes, sizes 100 and 95. Thank you for looking.
