These are lovely fitted blouses that I recently acquired, I’m leaning towards 1950s? The 1940s and 1950s labels shown in our resource are very similar, the 1960s label is quite different . They are all tailored in a similar manner with vertical darts in front and back as well as bust darts. They have not been clipped behind the mannequin, what you see is their actual shaping. All are from McMullen of Glen Falls, NY. The plaid one has a square cut armscye. The khaki and the white ones are a beautiful Moygashel linen!
