Vintage retailer 1950s lace jacket with organza neckline bow detail collared neckline lingerie blouse split back

This is a really interesting design of a black lace long tunic circa 1950s,
It has a lovely organza silk neckline with a side bow detail which sits at the shoulder retailer. The back has hooks and bars moving all way down and finishes with an open slit just 8” from base hem.
The neckline area closes with a hook and bar and press studs.
Sleeves and hem are also bound with silk organza. The lace is man made, and has some stretch to it. It has been photographed with a pale yellow slip ( to shoe the pattern). Slip not included in sale.
A unique shape which is a narrow A line, will look great worn over a dress or trousers.
Condition is great with nothing to note that detracts.

I would estimate this to fit a size UK 8 to 10. But please go by measurements.

Laying flat when closed up.
