This is a 100% cotton flannel shirt from "Houston," an American casual brand founded in 1972. The red and light blue color combination is cute. The size is listed as Free, but it's about a women's size S. I wore it perfectly, and I'm 150cm tall with an average build. It has cute cat-eye buttons. I think this size for women is rare. 【Brand】Houston Shoulder Width/Body Width/Sleeve Length/Length Shoulder Width...36cm Body Width...45cm Sleeve Length...56cm Length...61cm Material...Cotton #AmericanCasual
