I bought this dress: http://watters.com/Product/WtooBrides/13704
It's got a pretty low back and it's strapless. The longline bustier that the bridal shop provided at the time I bought it peeked out the top and in the back. I've been searching high and low for something that will work, but they either aren't low enough in the back or provide zero support in the front.
I'm thinking I'll either need to have cups sewn in or wear adhesive cups. Does anyone have experience with either?
