Birthday Cotton Thick Underwear Long Sleeve 80cm Set of 2 I think it can be used as underwear or pajamas. Upon closer inspection, there are small stains, so please check the images carefully. Used for one season, there is some pilling, but overall it is clean and can still be worn. I sometimes used a dryer, so shrinkage is also possible. Please only purchase if you understand this. Set of 2 soft beige and polka dot long-sleeved underwear. Thank you for looking.
