Essense of Australia D1417 Elegant unclassified dresses

I loved this dress when I purchased it and I still do. It's never been worn, though, because it was way too tight on me when it arrived. Long story short, my alterations person never told me it could be let out though I complained about the tightness all 3 fittings. I panicked a week before my wedding and bought a dress off the rack to wear because I was really concerned about being able to wear it for 8 hours comfortably. This is a beautiful all lace ivory mermaid fit dress with a sweetheart neckline and a chapel length train. There are buttons up the back that conceal the zipper. In the photo showing the dress from the back, the buttons are not done up so you see the zipper gap a bit.
