J. Crew Oxford Tunic: Outfit Help!

Ok, so I ordered this tunic after seeing an excellent review on Gigi's Blog. However, after receiving it, I'm kind of running into an issue of actually completing an outfit using it! Please help! I'd love some suggestions! After much rummaging through my closet, I came up with the following outfit ...

Top: Oxford Tunic, J.Crew, XS, shell
Bottoms: Paige Premium, straight leg, white
Belt: J. Crew skinny silver leather belt

I then proceeded to take this entire outfit off and put on something different because I just didn't feel like it looked great. HELP!

Any suggestions on what to pair this tunic with? Do you have it or something like it? How to you wear it? I'd love to hear it!
