This belonged to my great aunt, who was a seamstress.  I don't think the edging lace at the bottom is original, but it hangs well.  Could be removed.

Very pretty black machine made synthetic,  lace and an archetypal twenties style with diagonal zig zag seams joining skirt to bodice (hard to photograph!)

Probably had a pink slip under it - there are strap holders on the shoulders.

Damaged under both armholes - again hard to photograph, but could be repaired.
