Here's Juli Foster again, looking very intense in this picture from an editorial from the January 1978 issue of the American issue of Vogue.
The editorial was for the "Florida look," emphasizing clean colors and lots of suede. For fashion-minded women freezing in the Northeastern January, it was a soft sell.
Juli Foster is the only model in this editorial, which was photographed by Stan Malinowski. I featured a photo from a different editorial, "The Look of the Year -- New York, Paris, Milan," in this same issue of Vogue in my original post for Ms. Foster (second one from top) back in May 2011.
