Calla Blanche Valerie 17128 High-low unclassified dresses

I bought this dress because I felt like a princess in it but sadly had a bad experience with a seamstress, she basically said I was too fat to wear a dress like this because she said I should "eat celery and water for a week" rather than alter the dress at all. Needless to say it has only been tried on and hemmed to my height as well as a different clasp added in the back. It was never worn to my wedding I ended up getting a different dress after that sad experience. I just would like to try to get some money back on what I spent, open to offers!
