Wear your summer dresses during fall too. Just add a denim jacket and a scarf and change your sandals with boots. This is classic for me; little black dress with jean jacket to casual it down and tall boots, all in my colors :)
Cream over-sized tunic, blue denim skinny jeans, cream large clutch and brown cowboy boots with floral siding. I love this casual look! I would personally replace the cowboy boots with combat boots or riding boots!
