Shoe Help Needed!

So I am headed to my cousin's wedding this weekend and I am having a may-jah shoe dilemma! I can't find the pics of the two dresses I am debating on, but both look similar to this one worn by Lauren Conrad:


Picking out the dresses was the easy part! Picking out the shoes seems to be a whole different story! I don't want to go too-platform in fear of looking like a cheap hooker at an elegant wedding, but I don't want to end up in ballet flats either! So I need your advice/help as to what you think will look good with the dress style that is appropriate for such an occasion! Here are my top 3 choices:

Stuart Weitzman 'Greta' Peep Toe:

Michael Kors 'Pressley' Pump:

REPORT Signature 'Durant' Pump:

What do you think? Am I totally off base with my choices here? I know I don't have a lot of time to be picky, so to avoid going completely shoeless I would appreciate any thoughts you have! Ahh...the joys of being a girl!
