This item was originally sold as part of a set, but is now being offered individually. It's a cute cardigan with a single Usako point. This cardigan is easy to mix and match. The size is free size, but I felt it might be a little small for a child who wears 90cm. *Please note that this may vary from person to person. Although this item has hardly been worn, please understand that it has been stored at home. Please refrain from purchasing if you are concerned. I will try to ship it as soon as possible, but there may be delays as I have a 2-year-old child. Thank you for your understanding. Thank you for looking.
