This sweater is marked as a Medium, but fits absolutely perfectly as an XL or US46 due to the oversized fit AllSaints was going for (measurements in pictures). The fabric is a Wool / Alpaca / Polyamide blend and is super soft to the touch! If you’re into comfy, fuzzy sweaters… Or if you’re a huge fan of safety pins, then this is for you! Finally, the sweater is Responsible Wool Standard Certified. Honestly - It’s really nice!
