Vintage Colonial Rococo dress - made in 50s - XXS

Fake lace up front Rococo or Colonial heritage vintage costume dress. Heavy yellow fabric (upholstery?) in a mustard yellow costume with a metal zipper up side. I believe this was made in 1950s-ish. There's hand stitching on hems. No stains, great condition. Pics don't do this piece justice. 33 inches long 14 bust (28) 11 waist (22)
