Vintage 80's Prom Dress Roberta California

Vintage 80's dress by Roberta California, Size 11/12. The shiny black corset with soft boning leads down to the multi layered flouncy skirt, which has 3 tiers of black and white plaid and gingham, each trimmed with grosgrain ribbon. Made in the USA, 100% Acetate, pre-owned. This dress has been dry-cleaned and I don't see any stains, but there is some mild fraying along some of the skirt seams where the fabric meets the ribbon (see close up pic). This dress makes a bold statement and it's a rare vintage find! You spin me right round baby, right round!
