AI says With a bust measurement of 17", a waist of 13", and a length of 39", the dress would likely be a very small size, potentially a size 0 or 2.
The true color was difficult to photograph. It appears to be silver with a tint of gold. I photographed under lights, and outside. Please see the interior shots too. The hem looks to have been altered. Uncertain if this was a custom made dress. Truly unique.
