The pattern: Woman's Day 5042 (1952)
As you can read on the pattern envelope, this pattern was published in the August 1952 edition of Woman's Day Magazine. This crisp and contoured dress "for campus, office, and home" definitely looks all business. Note that it is a step-in dress, and has an eye-catching contoured double collar and ditto for the cuffs. Another clever aspect to this dress is that each sleeve is one piece (single seam), with the back being "kimono" style, while the front takes on a raglan aspect. Clever design!
And just for the fun of it, here is the back side of the clipping, full of fabric swatches in rich blue tones.
