After trying a couple of other wedding dress stores, I bought my dress yesterday from a bridal salon about an hour away. LOVED it once I walked out-- was absolutely certain that this was "the" dress, despite my wedding being more than a year away.
This morning I wake up and start getting a panic attack that I made the wrong choice, and couldn't stop thinking about another dress that I had tried on at the same store. I called up the poor bridal store lady and told her I was freaking out, and she was kind enough to let me come back and try both on. Thank god I did, since I realized that the dress I got was the right one.
I think my issue was that I started sending pictures of me in the dress to my BMs, and the pictures aren't great-- I look pudgy in the dress and it looks boring, didn't do justice to how beautiful the dress really is. I've decided I'm no longer allowed to look at pictures of me in it and I have to trust that it was the right one.

It's going to take about 6 months to come in anyhow, so maybe it's a good thing I got this done.
Anyhow, pics of the model in the dress (also doesn't look anything like the dress in real life, she's making a dumb pose below). Yay for checks!
