This is a cotton sweater from RHC Ron Herman. The material includes not only cotton but also acrylic, but it doesn't feel itchy like knitwear and is very comfortable to wear, with a soft feel. The color is white, so I think it can be used throughout the year. The size is listed as XS, but I wore it when I usually wore a size M, so I think those who wear sizes S to M can wear it without feeling too small. Thank you very much!
