If you love vintage clothing, chances are you’ve come across a dreamy, floaty piece made of chiffon. From 1960s cocktail dresses to 1980s formal gowns, chiffon is everywhere in retro fashion. It’s known for being sheer, light, and slightly shimmery—but one question pops up again and again: is chiffon polyester?
That’s a great question, and the answer isn’t as simple as yes or no.
Chiffon isn’t actually a material; it’s a type of weave. That means chiffon can be made from several different fibers including polyester, silk, rayon, and nylon. The fiber content changes how it feels, drapes, and lasts over time.
If you’re buying vintage to wear, resell, or simply collect, it helps to know what you’re working with.
Let’s break down what chiffon is really made of, how to tell what kind you’re getting, and why it matters—especially if you care about comfort, care, and sustainability.
