Thank you for viewing. The materials of this knit tunic are: Body Acrylic 100% Inner (striped fabric) Polyester 95% Polyurethane 5% Size Width: Approximately 48cm Length: Approximately 82cm Shoulder width is approximately 37cm, but the design allows for the shoulders of the sleeves to extend about 1.5cm on each side. Sleeve length: Approximately 54cm Approximately 34cm when folded and fastened with buttons The waist area is approximately 55cm in diameter, and when measured around the circumference, it's about 110cm. The tightness can be adjusted with the ribbon tie. There is no size label on the product, so I have classified it as a size M based on the measurements. It's a thin knit, but it has stretch and a tight knit, so it's not see-through. The color is a dark gray with some white threads mixed in, and the inner fabric has off-white and black stripes. The design is a 2-WAY type with adjustable sleeve length, and it's a knit tunic that integrates the knit and the striped inner fabric. The inner fabric is sewn at the shoulders and armpits, and it's only on the front. It's a relatively sturdy jersey fabric and is attached to the hem, so it doesn't feel flimsy and has a substantial feel. The buttons on the knit part can be fastened and unfastened, but you can usually take it off without unbuttoning them. You can adjust the sleeve length, so I hope you enjoy wearing it according to the climate. Since it is not new, please purchase it if you understand. Also, please note that returns are not accepted. I also have many other tops for sale, so please take a look. List of items for sale #nontan0317
