This decade saw a transition in hairstyles, from the more confined styles of the Victorian era to looser, fuller hairstyles. Curiously, both long and short styles were popular, with longer, free-flowing hair slowly gaining more converts as the decade progressed. Volume was the theme that ran through most of the popular hairstyles, regardless of hair length. Longer hairstyles featured hair parted in the middle (with a noticeable part), and long wavy tresses hanging below the shoulders. Shorter hairstyles generally began around the ears and poofed up over the head in several updo styles, often held in place with barrettes and adorned with bows, or large, wide hats.
First noticed on famous ballroom dancer, Irene Castle, the Castle bob swept the nation in the late 1910s and early 20s. Variations sprang up as the 1920s progressed, a result of women who began feeling their wild oats and experimenting with newfound freedoms of expression.
Formal hairstyles in the 1920s were often limited by the extremely short styles that were so popular then. To make up for this limitation, many women chose to wear wide-brimmed hats with elegant designs and bands. They wore their hair in very simple styles as a result. When a hat was not practical for a particular formal event, women often used curls and mini-updos to accentuate hairstyles that were crafted from rather plain-looking everyday styles.
