DKNY silk evening dress

I purchased this lovely dress in LA and have worn it several times. The tags have been removed. It is silk fabric from DKNY and is dry clean only for care. The halter top and wrap waist provide some flexibility as to fit and sizing. Has a leg slit on the side. The lie flat waist is 14” but easily fits a smaller waist with the wrap tie. The pit to pit is about 16” lying flat but again the halter tie provides some flexibility here as well. The colour is a very dark navy almost black. The size tag is missing but I would say this is a 4 based on fit and measurements. It has been dry cleaned.
