This is a Uniqlo fleece high-neck long-sleeved shirt. It's made of a soft, ribbed fleece fabric and has a simple high-neck design that's easy to layer as an inner garment. My child has only worn it a few times. I didn't see any noticeable stains, but it has been stored at home, so there may be some unnoticed dirt. Please understand this before purchasing. Feel free to ask any questions.
