hey. its totally normal to feel unsure about your dress. all the hype about it being "the one" and "that" feeling we're supposed to get when we put it on makes it hard for us to be certain its the right one and makes us question if we love it, know what im trying to say? the day of your wedding will def add the excitement, once your hair and makeup are done, your girls are dressed, everything will tie in, trust me. i honestly think your dress is gorgeous & that you're being your worst critic, like most women normally do- we over analyze everything.
however if you are 100% stone serious absolutely positive you dont like it and are not happy, well thats a diff story. that is something you'll have to try to determine and go from there. many girls get 2nd or 3rd dresses. you did have a few issues at first so maybe that's part of the reason you aren't sure. i love your dress though!
