I purchased this long-sleeved dress from Uniqlo. It's made of soft cotton smooth material. The size is 90. It's a floral pattern, so it's a bit difficult to see, but there is some yellowing on the front and the left elbow area. The cuffs are elastic, and there are snap buttons on the shoulders, making it easy to put on and take off. 100% cotton Floral dress Long-sleeved dress Baby Kids Girls Girl Sleeve Length: Long sleeve Design: Floral
