Dress dilemma

Okay so I am really stuck between two dresses. I initially went to David’s bridal and fell in love with one dress but did not experience the whole “I feel like a bride crying moment” at the time which confused the hell out of me because I just thought in order to find the one you must cry. So I went to a few other stores and tried one a few more dresses but nothing compared to the dress I loved at David’s bridal which is around $1350
Until today I tried on a dress at a boutique near my area and fell in love with the dress and veil because it completed the whole look of the bride. My Mom and I both cried, the only bad part is that I didn’t think I would love this dress as much as a I did because it’s a bit simple and out of my budget. The dress is $1400, veil $750 and alterations start at $700. My total budget is $2k for everything. Both dresses are beautiful mermaid gowns but have differences one is more dramatic at the bottom and the other one had a low back with a lot of beading but a simple bottom. At the boutique I was able to see the entire picture but at David’s bridal I wasn’t able to find a veil that really complimented the dress I liked which I feel is affecting the whole “the one” experience. So my question is how did you guys settle for the “one” ? As of right now I’m leaning more towards the dress from the boutique but I’m not sure I want to spend so much money on a dress for one day.
