Vintage 50s 60s Union Made ILGWU Long dress

The vintage 50s- 60s union made ILGWU long dress with Rhinestones. Vintage condition. The underpits are faded and a little damaged, and one rhinestone is missing and one part of fabric ( tape) is loose. So far, I see these small damages. Slit at back. There is weight on both sides of the slit where I circled it. I think overall this vintage dress is in great condition for the age with these minor damages. Please ask me any questions. I will try to do my best to answer.
