Simple and dainty classic black dress. The pictures do not do it justice! Gertrude Fashions is a boutique brand established in 1975, with the flagship boutique being in London, England. A vintage size 12 is significantly smaller than today’s size 12, so this dress may be closer to a 4 or 6. The material/fabric tag is not present. Measurements: Smallest part of waist: 13 inches (measured bottom of waist ribbon) Pit to pit: 18 inches Pit to hem: 35 inches As I was measuring, I noticed a place in the left pit where the seam has come undone, about a 1 inch spot. Can easily be repaired.
