Vera Wang nora Long unclassified dresses

I purchased this Vera Wang Nora dress from the Vera Wang store on Rodeo Dr. in 2016 and I has only been once on my wedding day. I had this dress altered to have a sweetheart neckline (shown in picture). I also had it altered to where the train of the dress ties up which I tied up after walking down the aisle. I haven’t had the dressed cleaned after my wedding so it does need to be cleaned. Please let me know if you have any additional questions.
