What a rare find!  This is vintage Vanity Fair, definitively 1960's with the light blue script tag which reads 'tricot all nylon'.  It's in a rare salmon color and in either new or near new condition!  Lace bodice backed by a sheer layer of nylon.  Scalloped edged hem with a side slit.   Just beautiful!  Size 34/measures small/x-small.
