PLEASE HELP!!! PLEASE ASNWER. ive picked my three favourite dresses for bride, bridesmaid and flower girls.?

For the bride I like the first dress (the second dress is fantastic too but not everyone has a great back, not saying that you don't and it's a little to baring), for the bridesmaid I like the first dress also and for the flowergirl I like the second dress. I would prefer white for the dresses, cuz I'm all traditional like that. :)
