This is a short-sleeved knit top from studio CLIP. The front is knit, and the back is made of a smooth, blouse-like fabric. The front also has the same blouse fabric underneath, creating a layered look. Materials: Knit section: 55% acrylic, 45% cotton; Fabric section: 100% rayon It's a size M, but it has a relaxed fit and is airy, making it cool to wear. The yellow color is cute. Thank you very much.
