It's that time of year around the world—twice annually when we transition from swimsuits to sweaters (fall) or coats to sweaters (spring). Sweaters are ubiquitous across geography and culture, like dumplings: every country, culture, human has an emotional attachment to them.

Here's your permission slip to wardrobe build without guilt or regret: As a case study, we spent way too much time online wading through hundreds of pages, editing for a specific set of factors—style, value, circularity, biodegradability, and fiber quality—netting a selection that is almost exclusively natural fibers: mostly cashmere and merino wool. Not the fast fashion or contemporary versions of these yarns, but the Italian, Scottish, Japanese luxury mill and brand versions. These are one-of-a-kind pieces across a size range, all in excellent, pristine, or new condition. Ranging from 42 to 795, with original retail prices between 400 and 3,500 USD—every sweater here is a fraction of its original price.

You'll find the highest quality cashmere and wool yarns from runway brands like Loewe, Bottega Veneta, Dries Van Noten, Jil Sander, Celine and Khaite, legacy luxury like Brioni, Berluti and Brunello Cucinelli, and contemporary cult knitwear brands like Iris Von Arnim, Begg & Co, &Daughter and The Elder Statesman. Some of our favorite selections are from Stella McCartney and Gabriela Hearst—both deeply consider and innovate around impact across equality, environmental regeneration, and circularity. Their inputs are already better than most, and your choices amplify that. This snowball of positive impact is how we make rapid, meaningful change.

Our edit is all from The RealReal—one of the most accessible places for preowned and new-unworn sweaters with insane value for what you get. They sort and grade items, which makes a significant difference when sourcing knits online. We've organized them by men's and women's as you regularly find them, but we think they're unisex—so we encourage you to look at the full edit as an everyone-can-wear-anything selection.

These are sweaters you keep for decades. You maintain them, repair them, treasure them. Even if it's not forever love, we've picked brands that hold resale value for another life with someone else. And if you've worn them out completely, they can be upcycled into new yarn or biodegrade back to soil after their full lifetime.

Mind-blowing fact from a recent wool conference hosted by Isabella and Fransccia Rossellini: Merino wool can be upcycled six times into new yarn before the fiber breaks down too much to be spun. This is the kind of information that changes behavior when you actually sit with it.

Our selected care tools below are critical to buying preowned sweaters and caring for all your sweaters—de-pilling is so satisfying, and the sweaters in this edit reward thoughtful care with long, rich wear.

LFG!
