This is a boa jacket purchased at a Patagonia store. It's a popular定番 item every year. My daughter wore it from the year before elementary school to the second grade. She's outgrown it. She wore it up to about 135cm tall, but the sleeves were a little short in the winter of her third grade year when she was 140cm. I personally feel it looks cute up to around 130cm. In the year before elementary school and first grade, it covered her bottom and kept her warm. We wore it for several years, but the boa is still in good condition. The size is: Please check the photos for the width, length, etc. The tag has been cut off, so the size is unknown, but I think it was a Kids' M. Please understand that this is a used item.
