Bonwit Teller/Jill Richards vintage Gothic gown

This dress is incredible. Very Gothic feel to the design. Long black 2 layered gown or maxi dress. This can be dressy or more casual . Incredible sheer silk like material sleeves. Super flowy sleeves. Satin trim at bustline and around and up the inside of sleeves. No size tag so will post some measurments. Pit to pit about 18.5 " across. 56" long,14" across waist and 18" across hips. This material is stretchy tho. I would guess it at an 8 or 10 .
