The sleeves can be rolled up. Recommended for times with temperature fluctuations. The white and light blue stripes are refreshing. You can roll up the sleeves and secure them around the elbows. Useful in the season when it's chilly in the morning and evening, and you sweat during the day. My child wore this when they were wearing 120cm clothing, so I've labeled it as 120cm. As there are no size or product tags, I will provide flat measurements. Length: 58cm Width: 35cm Sleeve Length: 35cm There is no material listed, but I believe the white part is cotton and the striped part is a polyester blend. There is no stretch. Please forgive any oversights as this is a casual inspection. Thank you to those who understand that this is a used item. Pattern/Design...Stripes Color...Blue Sleeve Length...Long Sleeve
