As shown in the photos, the lettering has faded due to washing, so I don't know the official size, but I remember it being free size. It's roomy for those who usually wear size M, and it should fit comfortably or even have some room for those who usually wear size L. It's perfect for wearing casually in the summer. Features a back ribbon and ribbon cuffs. No stains or tears. Made of wrinkle-resistant material, so it doesn't require ironing and is low-maintenance. fifth 3/4 sleeve striped ribbon shirt for women summer clothes fifth
