It's been washed at home.The collar is 37cm and the sleeve length (from the center of the back to the wrist) is 80cm, so I think it's a size S.It's not plain white; it has a subtle check pattern.Thank you.- Color: White- Design: Plain- Sleeve Length: Long sleeve- Pockets: One chest pocket on the left- Fabric: Check weave- Material: 65% Polyester, 35% Cotton ideal for everyday use. finest materials and excellent craftsmanship ensure long-lasting durability.
