Rare 1960s Drizzle for Bergdorf Goodman (Miss Bergdorf) vintage rain cape/jacket

Incredible early 1960s rain cape from Drizzle Inc for Bergdorf Goodman, Miss Bergdorf line. Fantastic condition (it’s wrinkled and has a *tiny* bit of wear but nothing significant). Flowing silhouette with batwing sleeves and button neck closure. No specified size but would fit a wide range, from perhaps 4-12.
