They got back to me today. The person confirmed the skirt would not look like the photo so I gave them another one that I had liked as a back up with a bunch of changes.
As far as the bust, they asked for a bunch of measurements, including the fullest bust, underbust, shoulder to nipple, distance between nipple, etc. I also additionally gave them an illustration of the dress with the height of the cup size measured out. I'm not too concerned that the width will fit but more so that it will be so short in the cup that I spill out all over.
They have a good policy that says if it isn't the measurements that I supplied them they will reimburse a seamstress to alter up to 50% of the dress. So I don't think if would cost that much more to fix if I had to I hope this is detailed enough..
