New Cocktail dress needs shoes!!! Stat!

I purchased this fabulous dress the other night at White House Black Market, and yes, Ari, I got a discount - even more than 5%!!!

Now I'm trying to decide on shoes... I like the red shown here but am really leaning toward purple or a deep teal. I'm also thinking I'm going to use a broach from my grandmothers collection that is made up of brilliant sapphire stones right in the center, as it's a bit low cut - EVEN for me. I also have matching earrings...

Any suggestions?
