2. Sézane

Best For | Feminine suit styles
Sustainability | Certified B Corp, OEKO-TEX certified sustainable & recycled materials, recycled packaging, responsible production, powered by renewable energy
Size Range | 0–16
Separates Starting At | $125 for bottoms, $225 for blazers

Sézane brings Parisian styles from the runway to your wardrobe. Made in ateliers throughout Europe, this certified B Corp creates timeless, feminine, and sustainable pieces perfect for the working woman. Nearly every fabric used is sustainable or recycled, packaged in recycled containers, and produced via renewable energy; the only lasting impact you’ll see is the one in your closet. We’re obsessed with Sézane’s blazers and pants, designed with deeply rich hues and classic patterns.


Best For | Wrinkle-free, machine-washable blazers
Sustainability | Certified B Corp, vegan, sustainable & recycled materials, most pieces made responsibly in Italy
Size Range | XS–XL
Separates Starting At | $160 for bottoms, $220 for blazers

Hands down, ADAY is our go-to for women’s workwear. This small biz has thought of everything when it comes to our 9-5 closet; both jackets and pants are wrinkle-free, thermo-regulating, and machine washable—yet fancy enough to impress any boss or boardroom. While we love its classic Strategy Blazer, we’re even bigger fans of its Dawn To Dusk Kimono jacket. Its relaxed silhouette can be cinched with a belt for additional accentuation or can be kept loose for a casual fit. All ADAY pieces are vegan, and most of these neutral capsule pieces are crafted with recycled fabrics. Double-win!

4. Amour Vert

Best For | Secondhand suits
Sustainability | Sustainable & upcycled fabrics, responsibly made in California, one tree planted with every tee purchased, recycled packaging, secondhand shop
Size Range | XS–XL
Separates Starting At | $188 for bottoms, $238 for blazers

Whether you work in academia, fashion, or on your own as an entrepreneur, Amour Vert pieces will work for you no matter the industry. The brand’s line of blazers and bottoms easily upgrade any outfit, from the Femme Fete Blazer to the plaid wool pants. No matter which style you’re leaning towards, every item is produced with sustainable fabrics developed by the brand itself. The price tags on these investment pieces can be a bit high, so we recommend checking out ReAmour, its secondhand marketplace for discounted finds (more than 50% off retail!). Our editors love to pair these blazers with distressed jeans for a chic yet casual look.

5. Kotn

Best For | Suit & skirt combos
Sustainability | Certified B Corp, ethical production in Portugal, sustainably sourced cotton
Size Range | XXS–XXL
Separates Starting At | $128 for bottoms, $248 for blazers

Inspired by North African fashion (given its roots in Egypt!), Kotn’s suiting collection effortlessly combines both the tailored fitted look with a baggy one…and it works! Every detail—down to the stitched necklines—has been made ethically by garment specialists in Portugal, using the best cotton twill around. Proceeds from Kotn’s sales go to support schools, farms, and families in Egypt with thousands of lives changed for the better—and more to come. You can find our editor wearing the brand’s slouchy suiting in Ginger—it’s a truly lifetime-worthy set. Just pay close attention to the inseam length on the trousers (a generous 32″) if you have shorter legs, as you may have to work with a tailor for the best fit!

Sewn locally in a fair trade workshop, every garment is made in small batches using only OEKO-TEX certified fabrics. As for the styles themselves, the brand’s silhouettes are professional and reminiscent of 1970s fashion; think Leon Bridges’ flared pants with Cher’s plaid blazer! Best of all, the team offers custom orders (at no extra cost!) if you need a specific size, and its Zero Waste Misfits program carries plenty of marked down items, too. OhSevenDays ships worldwide and is available at a number of stockists.
