Call me crazy, but I decided a long time ago that wearing dresses like this one is a lot more comfortable than wearing jeans on my casual days.  For the winter, this exaggerated shawl collar coat and over the knee boots can keep you warm while still being comfy.  The necklace would look great peeking out of the v-necks of both the dress and the coat, and I love how the bag pulls together the colors of the dress and the boots.
