I Need Your Help...

Just look at this dress...I love it! I seem to always find it hidden in my closet around fall time, but I have a few problems with it...

I think it's great by itself, but I'm not the by itself kinda girl. 
My problems are 
I don't know how to spruce it up,
What shoes to wear with it, 
if I can wear a cardi with it, 
or what necklace/scarf to wear. 

Any ideas?? I really want to feel stunning in it!
