I believe I purchased this at a vintage clothing store with an American aesthetic. It's a knit vest made of 100% acrylic. The tag has Japanese writing. The country of manufacture is not listed. Length: 47cm Width: 41cm It's compact, so it might be a KIDS size, but it's also stretchy, and the short length gives it a modern feel. Since it's vintage, there is some pilling. In the third photo, there is a small stain on the ribbing at the hem. It's not very noticeable, but please refrain from purchasing if you are concerned.
