Hmmmm. “I couldn’t possibly comment,” to quote Francis Urquhart in the British House of Cards series.
Here are two more 1933 illustrations from a different story — this heroine wears “Letty Lynton” sleeves.
In this image, the illustrator has omitted the huge, dark bow or flower at the waist of the gown that appears in the first illustration — probably to make Mimi’s dark-gloved arms more visible in the second picture. A clear composition is more important than consistency.
I didn’t have time to read the story, but we can have fun speculating about the plot from these illustrations. I’m guessing “widower with two daughters…. and a girl who needs a date…. and learns to be unselfish….” Or not.
