Wedding Undergarments?

So this is my dress, and I was told by my salesperson to get a bustier for underneath it. I tried a couple on that didn't quite fit right, as well as a strapless bra, but I feel like it will show in the back (the strapless bra DEFINITELY does). I know the dress back isn't super low, but I don't want to fiddle with it all night. My hair will be up, too.As you can see in the picture, I'm a fat plus-sized bride. Does anyone have any ideas about what to do to keep my boobs in place for the night? No bra is definitely not an option, and I don't think sewing cups into the dress really is, either. Help! And thanks in advance! via /r/weddingplanning http://ift.tt/2teyIsx
