to the wonderful invention of cardigan sweaters!
You can seriously never have too many
"Seems like long cardigan sweaters are still here to stay this Fall. Cardigans are light-weight, comfy, and convenient to carry as they can easily be folded and kept in our purses or school bags. They can be useful in air conditioned rooms or when the weather becomes more chilly but still not time to bring out our sweatshirts and coats yet. They can be worn with jeans, shorts, mini skirts, tees, you name it!"__ (http://pretty-lil-things.blogspot.com/)
