This is such a darling classic navy blue dress with small white polka dots! The collar is nautical inspired and is sewn in a double bow at the front of the scoop neck.

The print appears to be sheer polyester viole, and the whole dress is lined in dark navy blue acetate. The seams are pinked and reinforced with zig zag stitching, and the zipper is metal. I believe this vintage dress is from the 1960s.
