I believe I purchased this at Akachan Honpo. It's 100% cotton, made in Japan. I don't see any yellowing or stains, but there is some fuzzing characteristic of cotton. My child was a bit big, and they outgrew it quickly due to the season, so I don't think it was worn very often. - Design: Balloons, stars, and flag print - Colors: White and blue - Neckline: Round neck - Sleeves: Short sleeves - Closure: Snap buttons Thank you for looking.
