Short-sleeved knit made of multicolor acrylic blend material, size M. - Color: Multicolor - Size: M - Material: 68% Acrylic, 12% Polyester Thank you for looking. I am selling this item as I am decluttering my closet. The colors and pattern are very cute, and it is loose-fitting and soft, so it is warm despite being sleeveless. It is size M, but it runs large, so you can wear it with room to spare (I usually wear size L or free size). Please use the third photo as a reference for the color and pattern. I liked it, so I have worn it a certain amount, but please understand that pilling and snags are difficult to see and may be overlooked. This is a used item, so please refrain from purchasing if you are sensitive or looking for something like new.
