Frequently asked questions.

What is Reformation clothing made of?

Based on our analysis of 1,468 Reformation products, the average garment is 63% natural fibre. The most common single fibre is Cotton (in 33.3% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Is Reformation cotton?

Sometimes — cotton appears in 33.3% of the 1,468 Reformation products we analyzed, but it's usually blended with synthetics. Only 43.1% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Is Reformation 100% cotton?

Some pieces are. Of the 1,468 Reformation products we analyzed, 257 are 100% cotton (or near-pure, 95%+) — that's 17.5% of the catalog. The rest are blends.

How much polyester does Reformation use?

6.8% of Reformation products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is below average for fast fashion retailers.

Is Reformation mostly synthetic?

6.8% of Reformation products are polyester-heavy (50%+ polyester). Average natural fibre content is 63%, so the rest of the catalog is mostly natural-led.

Does Reformation use natural fabrics?

43.1% of Reformation products are nearly all-natural (95%+ natural fibre). A decent portion of their range avoids synthetic fibres entirely.

Is Reformation sustainable in terms of fabric?

Fabric composition is one factor in sustainability. With an average of 63% natural fibre, Reformation is better than many competitors on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.

Methodology: We analyzed 1,468 Reformationproduct pages, extracting the fabric composition listed by the retailer. Products are categorized by name keywords. Natural fibre percentage is the sum of all natural fibres (cotton, linen, silk, wool, viscose, lyocell, etc.) in each product's composition. Data is refreshed monthly.
