Navy short-sleeved shirt with a pocket, casual design. - Brand: GLOBAL WORK - Size: XL - Color: Navy - Design: Short-sleeved, with pocket - Style: Casual Thank you for viewing. It was too big when I received it, and I've already outgrown it. I haven't worn it even once, but there are no tags. There are wrinkles because it was folded after washing. Please purchase only if you understand. m(_ _)m
