Size says large, but the previous owner washed it incorrectly and shrunk it. I usually wear a medium, and it’s 3/4 length sleeves on me, shoulders decent, arms were a bit snug. I would recommend it for size small or extra small. It’s a cute sweater and looks even better on than in pictures. I can’t do wool or would consider keeping it. The knitted/crochet work is very pretty. Ruffle front still draped well. I think they put it through the dryer, because it’s almost lightly felted, but still wearable.
