Nouvelle Amsale Elliot in Ivory

Never worn Amsale Elliot dress in size 6. I purchased last summer from Stillwhite, new never worn, for my fall wedding. Arrived exactly as expected, however the dress ended up being too short, so I went with another option. It fits more like a 2 or 4 on the top. I am 5’5” and 115 lbs, and would have needed the top minimally taken in, and 2-3 more inches on the bottom (hit exactly at floor flat footed for me).
