Casablanca 1978 Party unclassified dresses

This dress sparkles like diamonds in church and reception hall lighting. The pictures do not show that. When I first bought it I was a size 4 and when I had my final fitting I was a size 2 and it still fit but had extra room in the bust area, there seems to be some flexibility with the size. It might even fit a size 6. I am 5'2 and wore 5 inch heels. It could work with less of a heel also.
