Vintage Pave de Paris maxi dress

This Company went out of business in 1989. I am not sure if this is a 70s or 80s, but I would venture to say 1970s. No size label but judging from how it fits the mannequin I would say it is an 8. This is an estimate. - chest 100 cm (at the point where the dress goes circumferentially) - waist 70 cm ( bottom of the bodice) - length 155 cm (dress laid flat and measured from top of halter strap to hem)
