I bought this intending to dress my child in it for their first birthday, but it felt a bit big, so I think it's around 90cm. I tried it on my 2-year-10-month-old daughter who weighs 13kg, and it fit without any issues! Please use this as a reference. Please note that this item is stored at home. I'm offering the item at a low price (＾ｖ＾), and to keep shipping costs down, I will compress it for shipping. Please be aware of this. If you prefer it not to be compressed, please contact me before purchasing! In that case, please understand that the shipping method will be changed and the price may increase m(__)m *bowing emoji* I will basically ship via Yu-Packet Post. However, I may change to Yu-Yu Mail or Rakuraku Mail without notice. I am also selling on other sites, so there may be instances where items are sold out.
