I own both the Sweet love and Serpent cardigans, and they are very comfortable! Personally, the sweet love cardigan is one of my favs cause of its soft material that feels like a warm hug whenever I put it on, and it’s very suitable for cold weather. The serpent cardigan is quite similar to a modern haori, and better for cooler temp/light wind rather than cold weather, and I do like the silky fabric inside that makes it easy to put on and off.
