The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.

What do Beyoncé, Hillary Clinton, and Gigi Hadid have in common? They can rock a power suit. And so can you.

Join their ranks by investing in a sustainable suit of your own. A stylish blazer paired with a fitting pair of trousers will help you feel like the boss you are, especially on days when you need a boost of confidence.

Consider these nine brands offering sustainable suit separates, from double-breasted blazers made from silk and organic cotton to ponte pants sewn from recycled polyester and linen. While we’re all for buying one suit that’ll match anything in your closet, we’re also eyeing these options below when we want to mix up our look.

Level up your look…and maybe your position, too. 😉

1. Amour Vert

Best For | Secondhand suits Ethics | Sustainable & upcycled fabrics (TENCEL, Cupro, Beechwood fier, silk), responsibly made in California, one tree planted with every tee purchased, recycled packaging, secondhand shop Size Range | XS–XL Separates Starting At | $98 for bottoms, $178 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 jackets easily upgrade any outfit, from the upcycled cropped plaid jacket to the golden silk blazer and matching 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 recco 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.


2. Kotn

Best For | Suit & skirt combos Ethics | Certified B Corp, ethical production in Portugal, sustainably sourced cotton, gives back to Egyptian schools & farms Size Range | XXS–XXL Separates Starting At | $98 for bottoms, $218 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 suit. Just pay close attention to the inseam length on the trousers (a generous 32″), if you have shorter legs you may have to work with a tailor for the best fit!
