I have a shelf in my closet just dedicated to cardigans. I am addicted to them, I have SO many. Once I find ones I like, I tend to buy them in multiple colors. This one that I'm wearing below, I have it in black and blue as well. They are just so versatile and since I'm always cold, I always have an extra one stashed somewhere.
Cardigan: Banana Republic
Shirt: Banana Republic
