I used these as undershirts. They are size 70. They show some signs of wear. They have been washed and stored, so they are a bit wrinkled, but I think the wrinkles will disappear after another wash. Only the Dumbo romper is from UNIQLO. The others are from Nishimatsuya. Some have noticeable pilling. Please judge from the photos. The gray monkey print is cracked.
