To me, the dress shopping was the hardest part. I took a bunch of people with me on my second trip to the dress shop, and ended up buying the one that everybody oohed and ahhed over, and that made my future mother-in-law cry.
It also followed the "rules" of all the wedding guides, that tell you what type of silhouette to buy based on your shape.
A few months later when the dress came in, it wasn't me. I agonized over trying to make myself like it, but then I ended up going out by myself months later (didn't tell anybody I was going) and finding a dress that I really loved. (FMIL still doesn't know I'm not wearing the 1st dress!)
So I say go with your heart & get what you really love. Don't feel obligated to bring everybody with you or follow the "rules" of the wedding dress guides, and you'll make the right choice.
