Just a single detailed illustration like this one gives a wealth of information about this blouse and skirt, with back and front views of the clothes and one of the hairstyles. I will break it down into close-ups of the details.
Starting with the skirt:
This is a “circular” skirt, with one seam in front and one in back.
I think the folds of fabric in front are a result of the sway-backed posture she is forced into by her corset:
In the three views of blouse-waist 1659, it is trimmed three different ways. However, the low-necked evening version is not illustrated.
The pattern description says the high neckline and sleeves are attached to the under lining, not to the parts of the blouse we see:
The illustration also gives us back and front views of one (enormous) hairstyle…
… the one for evening is decorated with a roses and a plume on top.
These illustrations were obviously influenced by the work of Charles Dana Gibson. Gibson maintained that he was merely reproducing the women he saw on the streets of America.
