Used for one season, so there is a feeling of use. Since my child didn't spit up or leak poop, there are no noticeable stains or dirt. As it was worn by a child, there may be faint stains if you look closely. Please understand this. Uniqlo underwear was strong and useful no matter how many times I washed it ^_^ Rompers underwear Long sleeves Front opening Snap buttons Born in autumn Born in winter
