a cute early 80s disco dress, by couture brand Saint Romei. 
made of silk chiffon, with burnout squares pattern of red and purple velvet and gold lame. 
it has an underlayer of black silk, that ends in a pencil skirt below the mail body. 
it has a bit of a peekaboo look, the outer chiffon layer covers the bust, but the underlayer has a plunging neckline so if someone is looking for it, they'll be able to spot cleavage.

overall great condition, but there's some damage to the lining at the neckline-one hole and the lining has pulled away from the outer layer near one shoulder. should be easy to fix, without it being noticeable since it's hidden by the outer layer. see 6th pic. 

MEASUREMENTS: 
no stretch.
35" around bust. 
28" waist. 
35" hips. 
37" long. 
labeled a size 8, not sure if that's in UK sizing or just vintage sizing, but it fits more like a modern US size 4, or a small.
