Sandro Paris Turtleneck sweater cape One Size

I'm selling a very, very nice Sandro turtleneck sweater, which has a cape over the shoulders and back. Basically, under the cape, the sweater's sleeve holes are open and bigger, so you just stick your arms out and then they're under the cape. There's no marked size on this, but I'd say it would fit anywhere from a small to a large, just based on the openness of the sides and the give you'd have. It just depends how tight you'd want it to be. Non-smoking, no pet home.
