Mission #1

Your mission, should you choose to accept it -

Make this outfit interesting:

This is one of my favorite summer dresses, and living in TX it's already warm enough for such a dress. I usually just wear it with the pictured sandals. I think it would look great with a cardigan, but what color? And jewelry? My first (and only) thought is silver bangle bracelets and silver hoop earrings. But I'd love to be able to take this from a simple little dress & sandals combo to a really chic outfit.

Any ideas?
