History of National Nylon Stocking Day

Wallace Carothers and a team of researchers at DuPont developed nylon in the mid-1930s. Before this invention, stockings were made primarily from silk or wool. Silk was expensive and prone to tearing, while wool was bulky and uncomfortable in warm weather. DuPont first presented the new “miracle fiber” to the public at the 1939 New York World’s Fair. The company marketed the material as being as strong as steel but as fine as a spider’s web, creating an immediate demand for a synthetic alternative to silk.

On May 15, 1940, department stores nationwide launched sales of the new stockings. During the first two days, women purchased approximately four million pairs. The success was short-lived, however, as the United States entered World War II and the government diverted all nylon production to the military for parachutes, ropes, and tents. This created a massive shortage, leading to “nylon riots” in 1945 when production finally resumed and thousands of women crowded stores to secure a single pair.

The development of nylon changed the textile industry by proving that lab-created fibers could outperform natural materials. It made elegant fashion accessible to everyone, regardless of their social standing or income level. Before nylon, luxury hosiery was reserved for the wealthy, but the mass production of synthetic fibers allowed working-class women to achieve the same polished look for a fraction of the price.

This holiday also recognizes a major milestone in industrial chemistry. The creation of nylon paved the way for modern plastics and polymers used in every sector from medicine to aerospace. Culturally, the stocking became a defining element of mid-20th-century style, symbolizing the transition into a modern, technologically advanced society. Even as fashion trends evolved toward casual wear, the stocking remained a staple of professional and formal attire.

How to Celebrate National Nylon Stocking Day

You can observe the day by wearing a pair of classic stockings or exploring the history of vintage fashion. Many collectors look for “fully fashioned” stockings, which feature the traditional back seam that was a hallmark of the original 1940s design. Sharing the story of the “nylon riots” with friends is a great way to highlight how much a simple garment can influence public behavior during times of scarcity.

Another practical way to celebrate is to learn about modern, sustainable hosiery options. While the original production of nylon had a significant environmental footprint, many brands now offer stockings made from recycled plastic or regenerated nylon. You can also spend time learning how to properly wash and store your hosiery to prevent “runs” and make your garments last longer.
