This is a long-sleeved, gown-style sleeper purchased from Conbi mini. It was great for reducing the hassle of repeatedly putting the blanket back on at night during the winter, as my child would kick off the covers. Used for one season during the peak of winter. I don't think there are any noticeable stains, but there is some pilling from wear. Please understand that this is a used item. [From the website] This striped sleeper with a cute whale applique can also be used as a gown, making it a great item. It's a convenient piece to have during the chilly season. Made of soft knit quilt material, the part that touches the skin is 100% cotton. It has snaps at the hem to prevent it from riding up. [Material] 74% cotton, 26% polyester (knit quilt) [Notes] Sizes 100-130 have 5 buttons and snaps to prevent riding up.
