Well guess what? Hate it no more! Just cut the back of the dress open and add a long triangle of lace. You can add about six total inches of width across the back of the dress without it being wonky and clumpy.
Here's the dress I found:
For $6.00. Seriously. How could I walk away from this?!
It reminds me of the one Julia Roberts wore to the horse races in Pretty Woman. Big part of my childhood.
I wish I had taken a photo of the back of the dress, but as you can kind of tell at the left, the back had a button closure.
I took the button off and folded the closing ends over, then sewed them down to make a V. I added a triangle of lace, measured from the top of the back neckline to the waist, skinny side down.
A zip zip at the sewing machine, a couple quick alterations, a strip of lace as a belt, and BLAMO!
