SHIPS turtle neck knit. The fabric is relatively thin, but I thought it was warm without being bulky. I think you can wear it casually for a long time. I am selling it because I outgrew it after purchase and it has been stored at home. Sleeve Length...Long Sleeve Neck...Turtle Neck Pattern/Design...Border I think it is equivalent to size M. Please use the following measurements as a reference, as they are measured by a amateur: Shoulder width...40cm Width...47cm Sleeve length...59cm Length...64cm
