Vintage fitted silk off-white beige shift dress.

Vintage fitted silk off white shift dress. Very pretty! It has almost like stripes of darker and lighter off white. See pics. No tags at all my guess is somewhere around a size 6 see measurement pics. I bought this at a vintage market and was told it was pure silk. Great condition one very small mark on outside and a slight darker spot on underarm see pics. Some small marks in inside liner not noticeable from outside K
