Whether you’re updating your staples or experimenting with new silhouettes, this is your guide to staying fashionable and mindful all autumn long.

Why Sustainable Fashion Matters More in Autumn

Autumn often brings an uptick in shopping: layering essentials, boots, and richer fabrics dominate wishlists. But with the rise of fast fashion cycles, this can also become a period of wasteful consumption. Choosing eco-conscious pieces helps reduce landfill waste, energy use, and carbon emissions, especially critical during high-consumption seasons.

The Environmental Impact of Traditional Fashion:

• Synthetic materials (e.g. polyester) shed microplastics into waterways
• Textile dyeing is one of the world’s largest sources of water pollution
• Fast fashion contributes to 92 million tonnes of waste annually

By pivoting to sustainable fashion during fall, you’re actively voting for better industry practices. And guess what? Today’s eco-friendly clothing brands have made guilt-free style more accessible and appealing than ever.

Fabrics to Fall in Love With

Choosing the right materials is at the heart of autumn eco-fashion. Look out for textiles that are sustainably sourced, biodegradable, and manufactured with minimal environmental harm.

1. Organic Cotton

Breathable, soft, and ideal for layering basics like t-shirts, turtlenecks, and leggings.

Why It’s Better: Grown without synthetic pesticides and uses significantly less water.

2. TENCEL™ Lyocell

A silky-soft fibre made from wood pulp, perfect for flowy blouses and midi dresses.

Eco Perk: Closed-loop production process recycles 99% of solvents.

3. Recycled Wool

A cold-weather classic with a sustainable twist. Great for jumpers, scarves, and coats.

Bonus: Reduces the need for virgin wool and saves energy.

4. Hemp and Linen Blends

Lightweight yet warm, these are excellent for early fall pieces like trousers and layering shirts.

Fun Fact: Hemp is a carbon-negative crop!

Trending Fall Colours with a Green Heart

Autumnal tones are timeless, but sustainable collections in 2025 are focusing on low-impact dyeing methods and natural pigments.

Palette Picks:

• Earthy browns and rusts — evoke warmth and pair with everything
• Olive and moss green — symbolic of nature and renewal
• Golden mustard — an unexpected pop that remains grounded
• Muted clay and terracotta — calming, versatile, and sophisticated

Hack: Look for garments labelled as “plant-dyed” or “low-impact dyed.”

Layering Smart: Sustainable Pieces That Work Hard

Autumn is all about layering. Prioritise high-quality, sustainable items that can be mixed and matched across multiple outfits.

The foundation of every autumn wardrobe.

2. Oversized Recycled Wool Jumpers

Perfect for cosy evenings or layering under a trench coat.

3. TENCEL™ Midi Skirts or Shirt Dresses
