Thank you for viewing! I purchased this at Costco several years ago and wore it 2-3 times before storing it in my closet at home. The size is listed as 3T, so I believe it's equivalent to 90cm-100cm. In our family, we bought and used it for a relative's wedding when our child was about two and a half years old. If you have any other questions or concerns, please feel free to comment. Thank you for your consideration! Immediate purchase is also welcome! *To reduce costs, the packaging materials will be shop paper bags, etc., and the item will be shipped in a compressed state. Please understand. If you are concerned about compression, we can ship it in a fluffy state for 2,000 yen.
