NWOT Gianni Bini Harper Satin V-Neck Sleeveless Ivory Bridal Slip Midi Dress

I purchased this dress to wear for my wedding after party, but ultimately decided to wear something else. It is brand new without tags and comes from a pet and smoke free home. The dress is elevated, but still comfortable, and has a lining that hit about mid-thigh. The dress is a US 2. For reference, I'm 5'6" and 115 lbs, and the dress fit perfectly.
