What the well-half-dressed woman was wearing half a century ago:
Were it not for the Really Big Hair, especially to the right, you might think this was a trio of slightly overgrown tweens at a slumber party. Certainly they’re not trying to sell you on the sexiness of these blouses: the big deal here, apart from the $4 price tag, is the permanent-press feature, still fairly newish in 1967. (Brooks Brothers had come up with wash-and-wear shirts in 1953, but it would be a couple of decades before permanent press would approach universality.)
M. Serman and Company put out blouses under a variety of brand names, including Alexa, Runway 1, and Windfall; they faded in the 1980s and were gone shortly thereafter.
