An Overview of Natural Fibers

Natural fibers are as versatile as our wardrobes: they can keep us cool, keep us warm, drape softly, or add texture. Classic natural fibers include plant-based fibers such as cotton and linen, as well as animal-based fibers such as wool and silk. There are also regenerated cellulose fibers such as Lyocell, viscose, and Modal. Although they’re based on natural raw materials, they’re technically processed into fibers. That’s why we’re dedicating a separate blog post to them.
In this post, we’ll show you what makes classic natural fibers special, where they come from, and how to care for them properly.

Caring for Natural Fibers: How to Keep Your Favorite Pieces Looking Their Best

wash or air out

Wash natural fibers as gently as possible: preferably in cold water or at a low temperature, with a mild detergent, and no more often than necessary. Often, it’s enough to air out a garment instead of washing it right away.

Drying and Ironing

Air-drying is usually the best option for natural fibers. Hang lightweight items loosely, gently pull them into shape, and it’s best to dry wool flat. Steam helps gently smooth out wrinkles—especially with linen.

Store

Store natural fibers in a well-ventilated, dry place, away from direct sunlight. Wool knitwear keeps its shape better when laid flat, while blouses, dresses, and linen garments can be hung loosely.

Which natural fiber is right for you?

The right natural fiber often makes all the difference:

  • Cotton—if you're looking for something soft, versatile, and easy to care for
  • Linen, if you want your Look to be Look , natural, and summery
  • Wool, if you want warmth, texture, and comfort
  • Silk—when it needs to be fine, flowing, and high-quality

In the end, what matters is what feels right to you—and which material fits your lifestyle.

Critically examined

Natural ≠ sustainable

Natural fibers are derived from natural raw materials. At first glance, this sounds particularly sustainable—and it certainly can be. However, the fiber alone does not determine how sustainable a garment is. Even among natural fibers, there are significant differences depending on how they are grown, harvested, processed, and cared for. Several factors come into play here:

  • Cultivation and Origin: How was the plant grown or the animal raised?
  • Processing: How much water, energy, or chemicals were used?
  • Dyeing: How was the fabric dyed or treated?
  • Transportation: Where was the garment manufactured, and how far did it travel?
  • Durability: How well does the material hold up with regular wear?
  • Care: How often and how gently is the item washed?

So it’s a good idea to check the fabric label, but that doesn’t tell the whole story. Our advice: Don’t just buy based on the fabric—consider how it feels, its quality, and how well it fits. A piece that you love, wear often, and take good care of is usually the better choice in the end.
