Rosemary Hallgarten Alpaca Sweater Open Front Waterfall Black Size M /One Size

Rosemary Hallgarten women’s Alpaca open-front cardigan sweater in Black. I would describe the collar as a ‘waterfall’ style. This sweater fits like a Medium, but I don’t see a size label. It could have been made as One Size, because of the open front style. I included multiple measurement pictures for reference. The alpaca fabric has plenty of stretch as well. Please see slideshow images. Thanks for looking!
