This is a flannel check shirt from BEAMS. It has a blue-based check pattern. Size M. The collar is button-down. I wore it often when I bought it, but I haven't worn it much recently, so I'm selling it. It shows signs of wear. Please purchase only if you understand that it is USED. Free shipping. Flat measurements (laid flat): Shoulder width: 43cm, Sleeve length: 62cm, Chest width (underarm): 54cm, Total length (from collar to hem): 70cm. Please note that there may be slight errors due to amateur measurements. Instant purchase is OK. Please ask any questions, unclear points, or concerns before purchasing. Also, I generally do not negotiate prices, so I may not respond to price negotiations in the comments section. Please understand that answering questions and shipping may be delayed compared to normal due to work or personal circumstances. Please be sure to check my profile as well. #BEAMS Color...Blue Pattern...Check
