The size options in the size selection above only went up to 160cm, but the product size is 170cm as shown in the image. Measurements taken flat (amateur measurements): Width: 52cm Length: 70cm Sleeve length: 60cm Material: 100% cotton I wore this with a vest (sold separately) for an elementary school ceremony for upper grade students. I liked this shirt and wore it afterwards, so there is a feeling of wear on the inside of the collar. Please understand that this is used and has been stored at home. Thank you. Thank you for viewing. #Polo by Ralph Lauren #Polo Ralph Lauren #Concert #Graduation Ceremony #Uniform #School Commute
