I would get the pair you think are cutest, and then a backup pair of flats you can change into for when they are unbearable towards the end of the night. I personally love the first pair!

If you choose heels and change out of them into flats, then you will have to get your dress altered for flats. Otherwise you will trip on the dress if it is altered for heels.
Oh my gosh they are all SO beautiful!! But yes, just like Michelle make sure to take into consideration of switching over from heels to flats. Talk to your seamstress to see what they advise
They are all lovely and I don't think you can go wrong with any of these pairs of shoes. They might not be comfortable to wear all night but they sure look good
