Short-sleeved knit made of multi-colored acrylic blend material, size M. - Color: Multicolor - Size: M - Material: 68% Acrylic, 12% Polyester Thank you for viewing. I am selling this to organize my closet. It has a very cute color pattern and is loose and soft, so it's warm even though it's sleeveless. It's size M, but it's large, so you can wear it with room (I usually wear size L or free size). Please use the third photo as a color pattern sample. I liked it, so I've worn it to some extent, but there may be some pilling or snags that are hard to see, so please be aware that I may have overlooked them. Please refrain from purchasing if you are nervous about used items or are looking for something in new condition.
