Purchased several years ago at a MARLMARL directly-managed store. Made with whole garment knitting, this item is comfortable with no seams. It's a 2-way design, allowing you to wear it with the buttons in the back. The website states it can be worn until around 4 years old, but I think it might be a bit small. I've worn it about 5 times, so there may be some signs of wear. This is a used item that has been stored at home, so please consider this before purchasing. *It will be folded and compressed for shipping. *There is no tag.
