Apologies if this is a repeat post, but I looked through the other shapewear posts and couldn't find anything quite like my problem...

When I went for my first fitting, I wore the strapless bra the bridal salon provided, which looked like this: http://www.dillards.com/endeca/EndecaStartServlet?N=1626433

However, you could see all the lines of the bra through my dress and it was giving me even-worse-than-usual armpit fat. My consultant suggested going braless, and while it improved the armpit fat situation, it seems to have created a number of unsightly lines in the bust area of my dress:

I went to both Dillards and Macy's today looking for something that would help, but everything I found was very uncomfortable and didn't seem likely to eliminate these lines, especially the huge horizontal one. Do you ladies have any suggestions for bras, shapewear, or even alterations that might get rid of these lines? 

@Jacqi:

Hi Jacqi-- oops, sorry, I mean to link directly to the seamless bra. That is exactly the kind my bridal salon had that could be seen through my dress. I am glad you didn't notice the lines! My dress has a corset back. I will try playing with it at my next fitting to see if that helps any....
