Linebacker in a dress Lol?

Hi everyone! I'm a long time "lurker" first time "poster"...lol anyways, my FH and I are getting married on 9/8/18 after 12 years together, wahoo!

I need help or suggestions.. I've always been very broad and bigger in the chest, shoulders and back areas and while I LOVE my dress, I feel I look like a linebacker in it LOL.. does anyone have any suggestions to lose weight or give the illusion of weight loss in those areas?

Thanks so much! ❤
