This dress is circa 1970 and has been hand made by an efficient home dressmaker.  It has a dramatic one shoulder asymmetric style and is midi length with a slight flare and  cute frill at the hem . The fabric is thick and decorated with ruched ribbon which would have been expensive to buy at the time.  

The dress  is unlined and has a little wear and that is normal due to its age , but its in fully wearable condition and I have personally washed it so its nice and clean.  

Its quite small at the bust measuring 32 max , waist 26 , hips a little bigger at 36 so if you are a size 8 it should be good , but measure your bust first to check
