This is a recommended set for those preparing for childbirth. The items are worth over 15,000 yen if purchased separately, but are offered at a bargain price as a set. The two items on the sides are size 3-6 months, and the two in the middle are size 0-3 months. GAP sizes run a little large, so they can be worn for a bit longer. *The two items in the middle were worn for a few hours each on outings. They have been washed, but the two items on the sides are unused. They are so cute, I don't want to part with them, but my child is quickly outgrowing them, so I hope someone will wear them! Thank you for looking.
