This long-sleeved shirt is a no-brand item. I purchased it online, but I've forgotten where I bought it. The black parts are knit. The cuffs have ruffles and are elasticated, so you can roll up the sleeves. Blouse Length: 61 cm Width: 46 cm Sleeve length (from neck to cuff): 67 cm It's a women's size S! If worn by a child, it would be about the size of a 160. Please feel free to ask any questions in the comments.＾＾
