Their clothing is designed to be low-maintenance (think wrinkle-resistant and machine-washable) without ever compromising on a polished, professional look.
The Style: Think of ADAY as the intersection of performance wear and workwear. The aesthetic is minimalist, futuristic, and highly functional. Their pieces are perfect for those who travel for work, bike to the office, or simply demand more from their clothing. It's intelligent design for an intelligent life.

6. Amour Vert
The Brand: The name means "Green Love" in French, and the brand lives up to it. Amour Vert’s primary commitment is to sustainable fabrics, partnering directly with mills to develop materials like TENCEL™ Modal, which are soft, beautiful, and far less impactful on the environment. For every tee purchased, they plant a tree, linking their commercial success directly to reforestation efforts.
The Style: Amour Vert excels at feminine, versatile pieces that can easily be dressed up for the office.

Their pieces are made in responsible factories from sustainable materials like TENCEL™, organic cotton, and deadstock fabrics.
The Style: Vetta’s aesthetic is modern, clever, and highly adaptable. A single blazer can be worn multiple ways, a dress can transform into a top, and a jumpsuit can separate into a top and pants. It's a pragmatic and sustainable approach to building a hard-working wardrobe that reduces decision fatigue.
Power Piece: The Blazer Dress. This incredibly clever piece can be worn as a chic, tailored dress, an open blazer, or a cropped vest. It’s the definition of a multi-tasking garment for the busy professional.

They are transparent about their carbon footprint and are actively working to become a carbon-negative company.

Power Piece: The Tree Runners or Wool Loungers. The Tree Runners offer a classic sneaker silhouette in a breathable, lightweight fabric, while the Loungers are a sophisticated slip-on. Both pair surprisingly well with tailored trousers for a sharp, high-low look.
13. Veja
The Brand: Before "sustainable sneaker" was a common phrase, there was Veja. This French B-Corp brand has built its reputation on radical transparency, fair trade sourcing, and the use of organic and recycled materials. They use wild rubber from the Amazon, organic cotton, and innovative fabrics made from recycled plastic bottles.
The Style: Veja sneakers are defined by their clean, minimalist design, marked only by their signature "V" logo. They have a more structured, classic feel than many other sneakers on the market, which makes them incredibly easy to style for a smart-casual office environment.

14. Theory
The Brand: A mainstream powerhouse in the professional wear space, Theory has made significant strides in sustainability with its "Theory For Good" platform. While not a fully "sustainable brand" in the way some smaller B-Corps are, their commitment to innovative, eco-friendly fabrics is noteworthy. They focus on traceable materials like their Good Wool and Good Linen, which are sourced from farms and mills that prioritize animal welfare and environmental stewardship.
The Style: Theory is synonymous with modern, minimalist, and perfectly tailored workwear. They are masters of the suit. Their pieces are investments—clean lines, luxurious fabrics, and impeccable fits that form the backbone of a sophisticated corporate wardrobe.

They focus on creating high-quality, timeless basics and have strong commitments to ethical factories and incorporating more sustainable materials like recycled cashmere and Clean Silk.
The Style: Everlane is the go-to for the modern minimalist's uniform. Their aesthetic is clean, simple, and functional. They offer everything you need for a business-casual wardrobe, from silk shirts and cashmere sweaters to perfectly cut trousers (their "Dream Pant" is a work-from-home hero) and leather flats.
Power Piece: The Clean Silk Relaxed Shirt. It’s a versatile, elegant staple that can be tucked into a pencil skirt or worn loose over trousers. It’s made in a LEED-certified facility using bluesign®-certified dyes, making it a more responsible choice for a wardrobe essential.
