This is a 90-size romper undershirt. I used to dress my child in this during the time when they were moving around a lot, but I was also concerned about their tummy getting cold. Long-sleeved undershirts with long sleeves seemed uncomfortable and bulky, so in our house, we used short-sleeved undershirts even in the dead of winter ^_^ I rotated through these, so there may be some signs of wear, but there are no noticeable stains or names written on them. I am also selling other children's clothes and shoes, so please feel free to ask about combined discounts ^_^ Bear, fairytale
