1950/1960 white and silver dress

Based on construction and the zipper I'd estimate about 1950s or 1960s White dress with silver flower and leaf motif No tags, zipper is fully functional but delicate Garment has been soaked and cleaned Underarm: 17.5" + a small amount of cup room. I'd estimate max bust would be about 37/38" based on how it fits my 38" bust. Waist: 14" Hip: approx. 19"
