Every piece of clothing you own is made of one of two things: something that grew, or something that was manufactured from petroleum. Natural fabrics come from plants (linen, cotton) or animals (wool, silk). Synthetic fabrics come from the same raw material as plastic bags, car dashboards, and soda bottles: crude oil. That distinction sounds dramatic because it is. And it affects how your clothes feel, how long they last, what they do to your skin, and what happens to them when you throw them away.
Here is the honest comparison between natural and synthetic fabrics, with no marketing spin and no hidden agenda beyond the belief that you deserve to know what you are putting on your body.
What Natural Fabrics Do
Natural fabrics breathe. Their fibers have natural structures, often hollow or porous, that allow air to circulate between the fabric and your skin. Linen’s hollow fibers ventilate actively. Cotton’s twisted fibers absorb moisture and release it into the air. Wool’s crimped fibers create air pockets that insulate in cold and cool in warmth. Viscose, made from wood pulp, drapes and breathes like a natural fiber while offering a silk-like smoothness.
Natural fabrics age well. Linen gets softer with every wash. Cotton becomes more comfortable over time. Wool pills can be removed, and the fabric lasts decades with proper care. The oldest piece in your closet is often the most comfortable, because natural fibers improve with time instead of degrading.
Natural fabrics return to the earth. At end of life, a linen garment decomposes within weeks. A cotton tee breaks down in months. They return their fibers to the soil without leaving behind plastic residue. The cycle of growth, use, and decomposition has been functioning for thousands of years without producing waste that lasts centuries.
What Synthetic Fabrics Do
Synthetic fabrics trap heat. Polyester, nylon, and acrylic fibers are solid and non-porous. They do not allow air to pass through them or moisture to escape. In warm weather, this creates a greenhouse effect between the fabric and your skin that makes you sweat more, not less. The “moisture-wicking” properties marketed by athletic wear brands are engineered workarounds for a fundamental problem: the fabric itself does not breathe.
Synthetic fabrics shed microplastics. Every time you wash a polyester garment, it releases tiny plastic particles into the water supply. These microplastics are now found in ocean water, drinking water, human blood, and breast milk. A single polyester fleece jacket can release up to 250,000 microplastic fibers per wash. These particles do not biodegrade. They accumulate. And the fashion industry produces over 60 billion kilograms of polyester per year.
Synthetic fabrics do not age well. Polyester pills, fades, and develops a thin, worn-out texture after repeated washing. It does not soften or improve with time. When a synthetic garment reaches the end of its life, which is usually sooner than a natural-fabric equivalent, it does not decompose. A polyester dress in a landfill will still be there in 200 years, slowly breaking into smaller and smaller plastic particles that enter the soil and groundwater.
The Comfort Test
The simplest way to understand the difference is to wear both on a hot day. Put on a polyester blouse at 9 AM and walk outside. By 10 AM, you will feel the fabric clinging to your skin, trapping moisture, and making the heat feel worse than it actually is. Now put on a linen blouse in the same conditions. By 10 AM, you will feel air moving between the fabric and your body, moisture being pulled away from your skin, and a sense of lightness that polyester cannot replicate at any price point.
This is not a subjective preference. It is physics. Natural fibers allow air and moisture to move through them. Synthetic fibers block both. In hot weather, this difference is the difference between comfort and misery. In cold weather, natural fibers like wool insulate through air-trapping rather than sealing, keeping you warm without the clammy feeling that polyester creates next to the skin.
The Real Cost of Cheap Clothes
Synthetic fabrics are cheaper to produce than natural ones. That is why fast fashion relies so heavily on polyester: it costs less per yard, wrinkles less, and can be produced at massive scale. But the lower price comes with hidden costs. Environmental costs from microplastic pollution, petroleum extraction, and landfill waste. Comfort costs from wearing fabrics that fight your body instead of working with it. And longevity costs from garments that wear out faster and need to be replaced more often.
A $20 polyester dress that lasts one season and sheds microplastics every time you wash it is not cheaper than a $159 linen dress that lasts five years, gets softer every wash, and returns to the earth at end of life. The price per wear tells a completely different story than the price tag.
THE DRESS TO POSITION
Every Dress To piece is made from natural or plant-based fabrics: linen, cotton, and viscose. This is not a sustainability campaign. It is a design requirement. Our collections are designed in Rio de Janeiro for women who live in warm weather, and natural fabrics are the only fabrics that work in the heat. The environmental benefits are real and important, but they are a consequence of choosing the right materials for comfort, not a marketing strategy layered on top of inferior products. When you buy natural, you feel better, look better, and leave less behind. That is the entire argument.

Here it's always Sunny!
