10 Sustainable Sweaters & Cardigans For 2023
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
Say goodbye to nights on the boardwalk, summer sunsets, and effortless tank tops, and hello to crisp evenings, chic jackets, and most of all, cozy sweaters! While we’ll miss the warmer days, winter invites us into cozier moments and a quieter headspace. Plus, the change in seasons gives us a chance to revamp and refine our wardrobes; we’re always looking for ways to be more mindful and intentional with our garments—blending form, function, and fair trade.
For fall and winter this year, we’re wearing sustainable sweaters from brands we love. These companies put people over profit while maintaining ethical, eco-conscious, and fair trade production practices. So cozy up!
For full fall fashion, pair them with some sustainable purses & boots. 👢
Best Overall | Most Affordable | Best Cardigans
1. Cuyana
Size Range | XS–XL; up to US 14
Our Pick | Alpaca Open-Back Turtleneck Sweater ($228)
Cuyana believes in “fewer, better.” This means the company responsibly produces its clothes, maximizes their wear through warranties and repair, and facilitates donating and reselling the pieces once you’ve loved them long enough. Cuyana intentionally selects factories that are near the source, so it can craft clothing with Pima cotton from Peru and silk from China. The Oversized Turtleneck Sweater features ethically sourced Alpaca wool which is then sewn together in a woman-owned factory in Peru.
2. NAADAM
Size Range | XXS–3X
Our Pick | Essential Cashmere Sweater ($75)
When it comes to sustainable clothing, we have to take into account a brand’s treatment of people, animals, and the planet. And NAADAM promises the “world’s fairest cashmere.” Sourced from Mongolia’s Gobi Desert, the company works directly with herders and provides hand-combing and veterinary care to its animals. This ensures their care and that you get the softest, most sustainable fabric—like its popular Essential Cashmere Sweater, available in 11 colors.
