Two-piece set of 100% cotton rompers, one with polka dots and the other with a pattern. - Color: Beige (polka dots) - Color: Cream (patterned) - Material: 100% cotton Thank you for viewing. These are Uniqlo rompers. As expected of Uniqlo, although there is some wear and tear, there's almost no stretching of the elastic or sagging, and all the buttons function properly. These rompers can still be worn, and since babies outgrow clothes so quickly, something like this is perfectly fine to buy on Mercari.
