Glossary

Terms we use when talking about sustainable fashion, fibres and care. · Updated 2026-09-24

A running list of the words that show up across the site. If a term here conflicts with how you use it, the page entry takes precedence on its own page.

GOTS
Global Organic Textile Standard. A certification covering organic fibre content and processing restrictions. Look for 'GOTS certified' (full product) versus 'made with GOTS' (lower threshold).
Blended fibre
A fabric mixing two or more fibre types (e.g. cotton–polyester). Blends are harder to recycle because the streams must be separated; pure-fibre or mono-material garments are generally easier to re-process.
Mono-material
A garment made from a single fibre type (e.g. 100% wool). Simpler to recycle than a blend, because there is no separation step. A useful signal when you are buying for end-of-life, not just wear.
Capsule wardrobe
A small set of interchangeable pieces, usually in a shared palette, chosen so most items pair with most others. The point is fewer, better pieces rather than a fixed count.
Organic cotton
Cotton grown without synthetic pesticides or fertilisers, under a recognised standard (GOTS or equivalent). Lower-input than conventional cotton, though it still uses water — 'organic' is not the same as 'low-impact' overall.
Bluesign
A standard for chemical input and resource use in textile production. A bluesign-approved fabric means the mill met limits on harmful substances and tracked water and energy use.
Fair Trade
A certification focused on labour conditions and farmer/worker terms, not fibre content. Relevant for cotton and other commodity fibres where the supply chain is long.
Regenerative
Farming that aims to leave land in better condition than it started — soil carbon, water retention, biodiversity. A newer and loosely regulated claim; we look for the specific practice, not just the word.
Pilling
Small balls of fibre that form on a fabric surface from friction. More common on lofty yarns (wool, brushed cotton) and on blends with short staples; often cosmetic, not structural, and usually manageable.
Composition tag
The fibre-content label required in most markets. The first fibre listed is the majority; reading it tells you care needs and recycling difficulty before you buy.
LCA
Life Cycle Assessment. A method that tallies a product's environmental impact from raw material to disposal. We cite LCAs when a brand publishes one; otherwise we rely on the fibre and manufacturing facts we can verify.
Circular
A model where a product is designed to be reused, repaired or recycled rather than discarded. Take-back and repair programs are the common implementations.
Fast fashion
High-volume, low-cost, trend-driven production with short wear life. The contrast case for a buy-less, buy-better wardrobe — not a category we recommend.
Take-back
A brand or retailer program that accepts used items (its own or any) for resale or recycling. Patagonia Worn Wear and Eileen Fisher Renew are common examples.
