From Wikipedia:

Victory rolls are a women's hairstyle that was popular throughout much of the 1940s, with a recent rise in popularity during the 21st century. The style is characterized by voluminous, sausage-shaped rolls of hair styled above the ears on the side of the head or on top of the head with an open curl facing forward. Victory rolls are closely associated with pin-up models and are achieved using various backcombing, rolling, pinning, and curling techniques.
