Sleeve length... 3/4 sleeves Material... Cotton Stripes 3/4 sleeves My child wore this a few times. Washed Although it's 3/4 sleeves, it has buttons so you can roll them up (see photo 4). When you raise the collar, the underside is blue (see photo 3). Please understand that this is a used item before purchasing. Also, since I don't have an iron, I will ship it as is, after washing and drying.
