80-90cm Unused, but the tag has been removed. It's very cute, but my daughter won't wear it, so I'm sadly selling it. I'm still hesitant to sell, so I don't plan to lower the price. It's 18 months, but the size felt perfect for a 2.5-year-old. There's a small stain on the collar in the third picture, but it's on the inside, so I don't think it's noticeable.
