the first one would bve okay, but don't wear any of the other ones. they're all white and will take away the extravagance of the bride's dress. and they resemble her dress too much. but wear the first one, and i think you'll be fine. =]
I like the third one the best (http://www.ever-pretty.com/PIC/XY08329-M.jpg) - I think it looks more like a dress for a day wedding than any of the other ones.
I assume that you are the bride? That being said, I would say the first one if you got in in a lighter color, like white, ivory or a really really pale pink. Anything in pink (unless it's very very pale) will look too much like a bridesmaid's dress. I love the style though. Good luck! : )
