I have waited a long time to think about this dress. As many have noted, it looks home made which can make it a little challenge as to dating it. My first thought was it is not 1940s, and I still think that is the case. While the style is a WWII style, the construction (to me) does not look at all like 1940s but seems more contemporary as does the fabric. I almost thought it was home made costume like "WWII red white and blue" uniform for a band or parade, or for a school play. Not sure if this is a home made "70s does 40s" or some kind of other thing. But I am leaning to it not being a true 1940s garment.
