Final Sale BHLDN Mina

I bought this dress from a woman in London, who had worn it for only 3 hours during her wedding ceremony/reception. I had it on back order in my size (4) through BHLDN, and it wasn't set to ship until 5/23/16, which was cutting pretty close to my wedding. So I purchased this dress and was planning on making needed alterations. The day before I was going to take it in to get altered, the size 4 dress arrived from BHLDN. So now, I have 2 gorgeous Mina dresses, and need to sell the 6.
