Vintage Perfectform plus size black lace trim slip top camisole

Vintage Perfectform plus size black lace trim slip top camisole. Comparing to others I’ve found I *think* it’s from the 50’s but I could be wrong. There’s no mistaking it is vintage though :) it’s a size 42 I’d say an XL / XXL. In excellent condition. It is 100% nylon and has adjustable straps. The brand is Perfectform.
