This is a Ralph Lauren shirt. The size is 100. The color is a cute blue check, and the fabric is 100% cotton, so it's gentle on the skin and soft. I was able to dress my child, who has sensitive skin, in it. It can be worn in spring, autumn, and winter. I received it as a gift, and it was useful because it could be worn for both clean and casual looks. It's in good condition with no noticeable scratches or stains, but it has been stored in a closet, so please purchase only if you understand that it is a used item. Flat lay: Length 46cm, Width 36cm, Sleeve length 41cm Pattern/Design: Check Color: Blue Material: Cotton Type: Long-sleeved shirt Gender: Boy
