Thank you for viewing! This is a set of two Uniqlo rompers. The gray one shows no noticeable stains. The one with the moon has stains on the chest, legs, and back, so please check the photos! The size is 70cm, but the tag on the moon one has been cut off. Would these be suitable for a spare set at daycare? Please consider purchasing only if you understand that these items are stored at home. Season...Winter
