Alfred Sung Dress #6881 if you want to find it online.
It's a size 18 but can be worn smaller or bigger because it is a lace up back.
It's ivory white and I have added straps that can be taken out. I will add a picture of the back to the comments. Make me an offer. Paid $1700 but obviously not looking to get the full price back whatsoever.
Love love loved this dress but I am not one of those girls that needs to have it hanging in my closet forever.
