The size is 150, but the fit is slim and tight, so please be aware. This is a short-sleeved T-shirt from THE NORTH FACE with a distinctive black and white color scheme. I've used it a few times, but my child quickly outgrew it, so I'm selling it. There's a black spot on the lower part of the front that won't come out even after washing. Please refer to the photos. - Brand: THE NORTH FACE - Color: Black/White - Style: T-shirt - Design: Short Sleeve - Material: Cotton Thank you for looking.
