I'm selling this because my child has outgrown it. I used it for two seasons ☺︎ I wore it quite often, but it's in great condition and I highly recommend it ☆ I think it's about three-quarter sleeves!! The cuffs are frilly and very cute. It's a sharp design, so it would be a perfect fit for a slender and small child who usually wears 120cm. I think it would fit better for children who are currently wearing 110cm. Please understand that this is a used item. When packing, I may compress it. Thank you for looking ☺︎
