Thank you for viewing! (^-^)/ ✅ Only tried on, but since it's white, it's been washed once. Just to be safe, I'm listing it as one rank below "new and unused." ✅ There's a button on the back. ✅ It's FREE SIZE, so for me, who wears M size, it's a comfortably loose fit. I think it might be a little big for those who wear S size. Flat measurements: Length: 63cm Width: 54cm (underarm) Pattern/Design... Solid Color... White Sleeve Length... Long sleeve Season... Spring, Autumn, Winter There may be oversight of small scratches or measurement errors. Please understand. Also, since it's a used item, I appreciate your understanding... Thank you very much!
