Postcard for General Dyestuff Corporation of a Woman Using a Dye Bath (1953) by General Aniline & Film CorporationScience History Institute
If you have ever knitted a hat or scarf, then you have used the same technology people have been using to create stretch fabric for a thousand years.
The looped stitches created by knitting gives cotton and wool fabrics their stretch. This kind of “mechanical” stretch is different from the stretch created by synthetic fibers.
Every fashion needs a stocking all its own! (1960s)Science History Institute
Nylon, the first synthetic fiber with stretch, was created by a team at DuPont in 1938. It quickly replaced silk as the fashionable fiber for women’s stockings. When the stockings were introduced on May 16, 1940, “Nylon Day,” four million pairs sold out within two days.
“I have read about the wonderful new stockings made from dirty old coal—surely you must have the angels working for you.” Letter from a customer in the 25th Anniversary of DuPont Nylon, 1939–64.
Spool of Rubberized ThreadScience History Institute
Following DuPont’s success with nylon, chemist Joe Shivers tried to create a synthetic rubber primarily for use in women’s foundation garments.
In 1959, Shivers invented spandex. The spandex in thread like this consists of two groups of molecules: one that expands to provide stretch, and one that is rigid to provide stability.
Like early women’s undergarments that made use of stretch fabrics, many “second skins” shape the exterior of our bodies. Stretch fabrics can be used to shape our bodies for fashion, health, and self-expression.
DuPont introduced spandex into the market under the brand name “Lycra.” While DuPont initially promoted girdles containing Lycra fibers (like the one depicted in this advertisement), by the 1960s, control top pantyhose had eclipsed them in popularity.
Breast cancer treatment sometimes requires the surgical removal of lymph nodes near the cancerous growth, a treatment which can lead to a dangerous buildup of fluid and swelling known as lymphedema. Patients can manage lymphedema with compression sleeves.
The lympheDIVAS sleeve, invented by two breast cancer survivors, not only reduces swelling but also features a comfortable seamless knit and a fashionable pattern.
Group Wearing Binders (2017) by GC2B Transitional ApparelScience History Institute
Stretch materials can help shape our bodies to better reflect our sense of self. Many trans, nonbinary, and gender nonconforming people use chest binders, which feature double panels of nylon and spandex, to flatten chest tissue.
From professional athletes to young children, many people make use of stretch fabric to facilitate movement. Innovations in stretch allow us to move with comfort, unencumbered and flexible.
NYLON... and the Jantzen magic touch! (1950s) by Jantzen Knitting Mills, Inc.Science History Institute
Mid-century and modern swimsuits would be unrecognizable to Victorian women, who swam in knee-length wool bathing dresses and full bloomers. Contemporary bathing suits are made of synthetic materials to allow for a tighter fit and a greater range of motion.
The suits in this ad were made with Lastex, an elastic yarn in which a natural fiber (like cotton or silk) is wound around a thread of latex, providing greater stretch to garments. It was registered as a trademark in the U.S. in 1931.

“I felt freedom, I felt empowerment, I felt like I owned the pool…” Lebanese-born Australian designer Aheda Zanett described the feeling of swimming in the burkini (a portmanteau of bikini and burqa) that she designed.
This swimwear provides women whose religious beliefs ask them to wear modest clothing the chance to swim and wade comfortably in public settings.
Modern full-coverage swimsuits also offer supercharged sun protection. This Coolibar hooded one-piece swimsuit for a small child is constructed with four-way stretch knit (polyester and spandex).
The tightly woven fibers physically block sunlight, but they're also embedded with zinc oxide or titanium dioxide for even greater protection against UV rays. This garment offers UPF 50+ coverage.
JogBra and Packaging (1977/1979) by Jogbra, Inc.Science History Institute
Running does not require much more than a pair of sneakers and for some people, a supportive bra. In 1977, Lisa Lindahl made the first sports bra out of two jockstraps.
Named the Jogbra, this bra featured a wide waistband, sturdy straps, and supportive cups.
Less bounce to the ounce! (1986) by JBI Jogbra, Inc.Science History Institute
This 1986 advertisement depicts the Sportshape bra, the successor to the Jogbra, designed to appeal to women who wanted a traditionally-styled, yet supportive bra for sports.
Scientists continue to innovate with stretch. Using new materials and new methods, researchers are developing cutting-edge wearable technology that can monitor, heal, support, and train our bodies.
Playskin Lift Assistive Garment (2016) by Martha HallScience History Institute
The Playskin Lift is an assistive garment for young infants with weakness or movement problems due to brachial plexus palsy, cerebral palsy, or various other forms of muscular dystrophy/atrophy.
This soft, comfortable, supportive stretch garment is designed to help strengthen arm muscles by providing light upward resistance. This prototype was completed in 2014 and can be custom made or even sewn at home, providing a low-cost physical therapy solution for families.
Imagine a wearable monitoring device that could perform comfortably, even in one of the most critical medical moments of many women’s lives: labor.
A new prototype “Bellyband” will monitor uterine contractions (and eventually, fetal heartbeat) for women giving birth or experiencing high-risk stages of pregnancy. Key to the design are the conductive threads that form a flexible, functional “antenna.”
Second SkinScience History Institute
Stretch garments form a second skin that can help us create the body we want or need. Thanks to chemists, chemical engineers, fashion designers, and garment workers, innovations in stretchy second skins have changed the way we live in our bodies and interact with the world.
