Fierce Critter, I followed your adventure with the first dress in the other thread - I liked the sound of the modifications you made, and was sad to hear it didn't work for you. But this new dress looks beautiful... the high waist and draping remind me of Grecian style.
I second the comment upthread about dangly earrings with a bare neck. And if you don't happen upon new shoes/bag today, don't stress about it... the black set will look great, especially for a formal (I'm guessing late) reception where you'll probably end up dancing the night away without them anyway.

And with your hubby in the black suit (a straight pocket square, maybe in red, IIRC?), you two will look quite fabulous and elegant together.
Not sure if you're considering a different hairstyle, but I keep imagining one of those side-swept, loose up-dos with the tendrils falling out - not too "promy" -kind of like
this (with just loose curls, if the braids seem too casual) - still sort of Grace Kelly-ish, but "up".
I hope you will post pics of you on the big night... have fun!
