What Is Polyester Made Of?

One of the most common questions surrounding what polyester is has to do with where it can be found. Following its invention in the early 1940s and its introduction to the public in 1951, polyester would go on to dominate decades’ worth of yearbook photos in the form of lightweight jackets, leisure suits, and brightly colored A-line dresses.

Today, polyester can still be found in dresses, blouses, and slacks, though most often in conjunction with other fabrics like cotton, wool, and nylon. Because of its remarkable versatility (and relatively low-maintenance care instructions), polyester is also found in a wide array of outerwear, athleisure, and fitness apparel.
