This is a used item. I'm selling it because my child has outgrown it. It shows signs of use, but it's relatively clean. The underwear on the bottom right is quilted and thicker. The green underwear on the top left is Uniqlo Heattech. Would these be suitable for a change of clothes at kindergarten, etc.? They still seem usable, so I'd like to pass them on to someone. Any items with names written on them will have the names blacked out. I will wash them at home before shipping. Thank you.
