Excellent, simple black Victorian hat. I can feel a stiff base inside, like a buckrum. Wire frame around the hat. The silk is gathers on the back of the hat and there are short ruffles of silk around the face. It seems like the back of the hat is bumped out to accomodate a hair bun. Long chin straps, silk lining.
CONDITION: The hat is in excellent condition. No flaws seen on the outside. There is some residue like glue on the lining.
