She has a hairstyle the name of which I do not know, but it is seen again in the 1980s.
It's a style that is usually shaved close along the sides and kept long on top, sometimes with masses of curls bunched up. On the ladies, it's usually an updo pulled taut so they don't have to commit to shaving off the sides.
Here's Martha Raye sporting it in the rhumba number from College Swing. The sides of her temple appear shaved, but they are not.
Now from the front. See the masses of curls piled atop her head?
The young man on the right is Harry Watson in A Damsel in Distress (1937). You can barely see it from this terrible screen shot, but his sides are shaved.
This hairstyle made a leap forward and became popular again fifty years later.
Here in the 1980s, Tricia O'Neil sports a similar hairstyle in Season 2, Episode 11 of the TV show "MacGyver." Hers is a fuller version of it. Closer to Watson's than Raye's. You can't really see the sides in this shot.
It's enjoyable to see great fashion recycled. However, I have no idea what this hairstyle is called. Do you? Please let me know in the comments.
