Summer Dress to Work

I usually think this dress is far too summery for the office. But I do work in a casual office & it was pretty hot out. While a cardigan can't make everything office-appropriate, I think this didn't do too bad.

What I'm wearing:
Black cotton tiered sundress, Coldwater Creek | Black & white floral-print cardigan, Black House White Market | Black kitten-heel shoes, Aldo | Painted-black shell necklace, bought in Florida | Black & white striped bead earrings, Kohl's | Black & gunmetal cocktail ring, Icing
