Merino wool, viscose, Angora and Cashmere. Sweater is fitted. It’s a medium, and it fits like a fitted medium or a more relaxed small. Sweater is imperfect but is still in beautiful usable condition. Buttons are mismatched! It’s charming. I don’t know if it is deliberate or not. Some of The buttons have chips on them, but they are functional and cute and I’d leave them. There is a spot where the beads woven into the orange embroidery are missing, but it’s minor and not noticeable. Sweater is still very pretty and well made!
