Vintage 80s does 1930s cream draped jacket w/ floral lace back

Gorgeous vintage 1980s romantic revival piece mimicking a classic 1930s Hollywood glamour boudoir jacket. Features an ultra-fluid, likely rayon, drape that falls elegantly. The open front boasts cascading ruffled lapels accented with delicate fabric rosette details near the shoulders. The standout feature is the stunning, completely sheer floral lace back that adds a beautiful contrast. Perfect for layering over a silk slip dress, a simple cami, or pairing with denim for a chic coquette, or romantic cottagecore look.  No tags at all, but it does feel like a heavier rayon; flat sizing suggests it would best fit a medium or smaller large. See photos for details and flat sizing.  Approximate flat measurements: pit-to-pit: 20.5” shoulder to hem: 19-23” (slightly shorter in the back)
