Thank you for viewing. This is a Comme des Garçons long-sleeved shirt with a black base and floral pattern. I purchased it from a used clothing store over 10 years ago. The material is unknown as the product tag has been cut off, but it is a thin, sheer material. I think it's perfect as a light outer layer for spring and summer ☺ Please check the design, condition, and size in the photos. It has been stored at home for a long time. I am looking forward to purchases from those who understand used clothing and are not overly concerned about minor imperfections.
