Off-brand find and coord help!

Hello!
Well tonight while studying for finals, I decided to try on a dress that I got from Target, and while doing so, I thought to myself, "Well, why not pop a petticoat under this thing??"

So I did. And this is the result:


I was kinda going for a county~sweet kinda look. Think it works?
 And this is where the coord help comes in,
Im kinda at a loss of what to coordinate this with, and since it is a little low cut on the top, I defiantly need some help:)
Thank you!
