The lace is incredibly fine and detailed likely Chantilly Leavers Lace (possible Satin Blend), with delicate floral motifs flowing seamlessly through the bodice and down into the spectacular train. The gown features a beautifully shaped V neckline, structured shoulders with original shoulder pads (a hallmark of late-1930s styling), and an authentic period WICO side zip — a wonderful detail confirming its era and quality.
