Women's 50s 60s vintage rockabilly, pinup A line cocktail swing dress, size medium. This classic navy blue and white polka-dot knee length swing dress can be styled up or down for any occasion. This dress has a hidden back zipper and a crinoline sewn in the skirt. It is vintage and has a little yellowing under the arms and shoulders as shown in the picture. I absolutely love this dress but it doesn't fit me anymore. The tag doesn't say, but I believe it is 100% cotton. ptp 17.5" waist 13"
