GROOVY vintage late 60's, early 70's Jack Hartley slinky halter maxi dress.   Hard to find larger size!   100% nylon...stretchy fabric...like a swimsuit fabric!  AMAZING pink and purple design with an open back.  Bodice is lined.   Size tag reads 13/14, but please check the measurements carefully.  All measurements have been taken with the dress laying flat, so may need to be doubled.
