These are UNIQLO's children's Relax Pants (Rirako). They don't sell this type of Relax Pants anymore, but they were very convenient as summer loungewear. With pockets I basically only wore them indoors, so I didn't see any stains, but please purchase them with the understanding that they are used items. ^_^ #UNIQLO #RelaxPants #Floral #Loungewear #Roomwear #Pajamas #Blue Gender: Girls
