Love the blue lace dress on you - and since I hate shopping for just one event, I'd vote to go with those Poetic License shoes and add a little arm bling that maybe repeats the green? Something like one of these?

Shannon keeping in mind that I'm quite partial to your PL shoes, one of the reasons I like them with that dress is that they maintain the retro vibe which is very you and they reflect your personality. The shoes have a bit of bling and IMHO are more interesting than a metallic shoe.
