I called RK Bridal this morning. They cannot take the dress back unfortunately, but the lady was so nice. She said for me to come in, they will measure me and see what they have in stock. She also said she will make a few calls to make sure they get me a new dress asap. I feel like she really cared. I know I don't have a dress that fits yet, but I feel better that there will be a resolution.
Good luck. I'm sure it will be fine. They can do wonders with fabric.
Good luck! My dress wouldn't fit over my boobs either. They were able to let it out. There is usually a little more material in the seems up there than in the rest of the dress.
