Long-sleeved shirt made of 100% cotton for comfortable wear. - Size: L - Material: 100% Cotton Thank you for viewing. Although it is listed as size M, it is a bit large, so I am listing it as size L. It has thin gray stripes. It is 100% cotton and thin. My husband recently purchased this, but it was too big, so it has only been tried on. It has been washed and ironed. It's perfect to wear alone this autumn. It would also be good to wear under a knit in winter. Flat measurements: Length: Approximately 72.5cm Width: Approximately 60cm Thank you.
