Mon Cherie beaded and sequin maxi slip dress

this beautiful dress I believe is silk, but I can’t find any fabric tags. Beautifully beat it in circular wave like swirls in glass seed beads barrel, beads, and sequins. There are bones at the side to help hold it in place and a double inset bra cup if you only want one, it’s a couple scissor snips to come out. Dress is in excellent condition. There are beads missing in several very small places. I don’t believe it affects the look at all, but you may so please look closely. I photographed the two largest one on the left hip and one under the arm. The dress has a slight train about 6 inches longer in the back
