Other Metallic unclassified dresses

This is a beautiful vintage 1989 dress that doesn't have to be sized perfectly to look beautiful.  I was between and 8 and a 10 when I wore it.  Has a long train that pins up in the back.  I am 5'6" and wore it with flats, but would look better with heals.  It was worn once and then dry cleaned and vacuum sealed.  It has been boxed like that for the last 30 years.  I would love to see someone else get some joy out of it!
