Champagne satin slip dress jeweled front cross straps back size med 90s vintage

beautiful v neck low cut satin slip dress I believe is from the 90s. jewels embellishment in the front deep low cut open back with crossed spaghetti straps, no adjustable. fit and flare style. I love this dress but it's big small for my chest, (size 34A for reference), I need more to fill it out. no lining originally made as sleepwear... but that's not how we do it today, is it??!! Mannequin is a size 4 for reference. 100% polyester machine was cold, gentle. tumble dry low or lay flat. approximately 16.5 inches ptp (at that middle seam) 34 inches long (from top of strap to hemline)
