This item was purchased as a used item. Items ① and ② were used once each. Items ③ and ④ have not been used. Item ③ has a small stain on the collar. Items ① and ② were worn by my child until they were 7 months old, so I think they can be worn for a longer period than the size indicates. I will offer a discount if you purchase other children's clothing items I have listed together.
