Thanks again to all the input and advice. I decided to keep the dress I bought for work and possibly the pre-wedding BBQ that I am going to w/other out of town guests etc the night before the wedding.

This is what I decided to go with:
I bought the heels at DSW today and will figure out jewelry later.
