How Can I Accessorize My Navy Blue Prom Dress?


I bought this dress from PromGirl.com about 2 weeks ago....and I really need help accessorizing it.

The dress: http://www.promgirl.com/_img/PRODUCTS/12…

The dress is navy blue, strapless. and long (fitted)

I was wondering how I can glam it up so that I look elegant and classy.
The ideas I have is to buy an wide belt with diamonds and place it over the flower or ever apply a thick ribbon and tie it so a bow forms in the back.....please help (If those ideas sound bad please let me know.)

What color shoes should I wear? necklace? earings? Hairstyle?
Please Help :)
