This is a beautiful little ivory possibly Dicel Grecian style dress from the 1960s.  The sleeveless dress has a fitted bodice with a wide neck at the front and a scoop neck at the back and a dramatic drape diagonally across the front and hanging from one shoulder, edged with gold Greek Key pattern braid, a fitted waist and a straight skirt with two rows of matching braid at the hem.  There is a long metal back zip, the bodice is lined and there is a split to one side of the hem.  There are no labels in this dress - I have shown it on my size 10 mannequin which it fits nicely - measurements are as follows : Pit to Pit 48.5cm (19") approx / Shoulder to Shoulder 43cm (17") approx / Waist - side seam to side seam 36cm (14") approx / Hip - side seam to side seam 46cm (18") approx / Length - nape to hem 95cm (37.5") approx.  Please note this is a genuine 1960s dress and has been worn and is not perfect - it has been altered at some time - the skirt lining has been removed and there are some repairs to the waist and hem - see final photos - the waist repairs could easily be disguised with a belt and the hem could be altered.  This is still a lovely dramatic dress.
