Reversible iridescent black silk evening coat

This one-of-a-kind coat was designed and made for a local boutique. It is black on one side and iridescent teal/purple on the other side. Both sides are embroidered with dragonflies. There was no size or any other tag. I am a size 8 and wore it comfortably, but I believe it could accommodate sizes 6 to 12 due to its loose-fitting design.
