The label has been clipped from this bra so I don’t know the brand. Judging from the style it could be from the 1960’s or 70’s. The size is around 36C or possibly D. The smooth satin cups are underwired and low cut. They have medium fiberfill padding and have a diagonal seam. The neckline edge is scalloped and has some decorative floral embroidery. The straps adjust in the front and have a short elastic section in the back. It fastens in back with a single hook and three eyes. The eyes are spaced wider apart than in most modern bras, as can be seen in the picture shown next to a modern bra.
