I selected the heart shaped yoke, but because I used the same fabric throughout I joined the back yoke and back pieces together omitting the seam.
I added some narrow pink ribbon to outline the heart shape too just to give some more definition.
One extra addition I made was to add a self bias trim to the neck edge. The pattern called for the neck edge just to be folded over, but I wanted something more defined. I simply cut a 1 1/2" bias strip, measured the required length needed , joined the edges together folded it wrong sides together and then serged it to the neck edge.
Here is a close-up of the fabric which isn't quite so obvious in the full-length photo.
