My super long cardigan from Old Navy is basically like wearing a big blanket. It’s so soft and warm, and it’s actually pretty heavy for a “cardigan”. It’s on sale now for $11, but there are limited sizes available in this exact color. I actually ended up finding this on the clearance rack in the store, so you may want to check your store to see what goodies they have on the clearance rack!
