Oh and I wanted to add after reading all the other comments-
When I first tried on my dress, I cried and cried. Not because I liked it, but because I thought I looked terrible. I wasn't able to take pictures the first time I tried it on because of store policy, but when it came in after I purchased it, I took pics and HATED the way I looked.
There was no making me feel better either. I tried it on again when I got home (meaning out of the unflattering florescent light) and took pictures over. I felt much better but still not 100% confident.
The day of the wedding, I didn't even have a care in the world. I felt beautiful because I was so overwhelmed with my emotions. I didn't even think about all my insecurities once. I felt beautiful. I believe you will find yourself feeling the same way as well.
