I had my first dress fitting, and I haven't gained a single pound since I ordered my dress and had a special muslin fitting that took my exact measurements. When I put on the dress, it felt tight on my upper rib cage right underneath my breasts, so much so I had trouble breathing. The alterations person told me to wear it for 20 minutes to see if I started to feel better, and I did notice that the dress felt a little more comfortable. She isn't going to let it out now, but I'm wondering if it's supposed to be that way. She said this happens to a lot of brides, and if they let it out, they later complain that the dress is too loose. But I don't know if she's telling the truth or if it needs to be let out. Any suggestions? Has anyone gone through this? Thanks!
