New Halston Heritage evening gown

This is new and never been worn but there are slight flaws from storage. It’s “slate grey” kind of has a pale bluish tone to it. Beautiful! IMO Halston Heritage runs a tad big, should fit a 0 or 2. The dress is very long and will probably need to be altered, and the very bottom is where there are faint stains as pictured so it shouldn’t matter anyway!
