Vintage 40s 50s Navy Blue Polka Dot Shirtwaist Dress Rayon Rockabilly Moonglow Buttons M L

If you love vintage with a little bit of mystery, this dress is for you.

Hailing from the late 1940s or 1950s, this navy blue polka dot beauty features a classic shirtwaist silhouette that never goes out of style. The fabric feels like a quality vintage Rayon blend—cool to the touch with a lovely drape—and the dress is fully lined for structure.

The Details: The front closes with stunning, original glowing blue plastic buttons (often called “Moonglow” buttons by collectors). But the real quirk is on the inside: a row of small white buttons lines the inner lapel. These were originally used to attach a white lace or pique collar, allowing the wearer to wash the white collar separately from the dark blue dress. While the original collar is lost to time, you can wear the neckline open as-is, or button in your own lace trim for a custom look!
