The style of the dress reminded me a lot of Zooey Deschanel, so I've styled the first outfit with a bit of an indie flair. Perfect for a fall day, the suede jacket helps to make the dress a little less "young" and adds a little edge. And how fantastic is that feathered butterfly headband?
The second outfit styles the dress to look like separates. Remove the tie belt on the dress, top it with a v-neck sweater so just the collar is peeking out and add a pretty sky blue belt. The peacock feathered hair barette would look great pinned to one side with your hair up in a messy twist or beehive.
