Top 10 'Values-Driven' Sustainable Brands to explore for Your 9-to-5 Wardrobe Upgrade
Let's be honest. How many mornings have you stood in front of a closet overflowing with clothes, yet felt you had absolutely nothing to wear to work? It's a familiar feeling of being uninspired, stuck in a rotation of the same few "safe" outfits. This fashion fatigue often stems from a disconnect between what we wear and what we value. Our 9-to-5 is where we spend a huge portion of our lives; shouldn't our work wardrobe reflect not just professionalism, but also our principles?
The good news is that the landscape of fashion is changing. The rise of the conscious consumer has paved the way for incredible brands that are proving style and substance can, and should, coexist. We're talking about "values-driven" fashion—brands built on pillars of ethical production, environmental responsibility, and timeless design. Upgrading your work wardrobe is no longer just about acquiring new pieces; it's about investing in a collection that empowers you, tells a story, and aligns with the future you want to see.
Here on the Goh Ling Yong blog, we believe that a powerful personal brand starts with intention. Choosing to support companies that do good is a profound statement. So, if you're ready to transform your 9-to-5 style from mundane to meaningful, you're in the right place. We've curated a list of the top 10 sustainable brands that will help you build a professional wardrobe you can truly be proud of.
1. Eileen Fisher
For the Architect of Timeless Elegance
Long before "sustainability" was a buzzword, Eileen Fisher was building a brand on its very principles. Their philosophy is simple yet revolutionary: design beautiful, timeless clothing meant to last a lifetime, using materials that are kinder to the planet. This isn't about chasing fleeting trends; it's about creating an elegant, cohesive system of dressing that works for you year after year. Their commitment to circularity is truly industry-leading, with programs like "Renew" and "Waste No More" that take back old garments to be resold or transformed into entirely new creations.
Their aesthetic is one of relaxed sophistication. Think luxurious fabrics like organic linen, silk, and washable wool crepe, cut into flowing silhouettes that are both comfortable and impeccably chic. For the office, Eileen Fisher is a goldmine. Their pieces are the building blocks of a versatile, high-quality capsule wardrobe that can take you from a client presentation to a gallery opening without missing a beat. They prove that sustainable fashion can be the epitome of understated luxury.
- Upgrade Your Wardrobe With: Their iconic System Pieces, a collection of simple, versatile shapes designed to be mixed and matched endlessly. Start with a pair of their Crepe Slim-Fit Pants—they have the comfort of a legging but the polish of a tailored trouser. Pair them with one of their Silk Georgette Bateau Neck Tops for an effortlessly powerful look.
2. Cuyana
For the 'Fewer, Better' Minimalist
Cuyana's motto, "Fewer, Better Things," is a powerful antidote to the fast-fashion mindset. This brand champions the idea of an intentional wardrobe, where every single piece is chosen with care, loved deeply, and worn for years. They focus on premium materials sourced from around the world—Italian leather, Peruvian pima cotton, Mongolian cashmere—and partner with skilled craftspeople to create items of exceptional quality. Their commitment to sustainability is woven into this philosophy; by creating seasonless, durable pieces, they encourage a culture of buying less and valuing more.
The Cuyana style is clean, modern, and feminine. It’s for the professional who appreciates subtle details and impeccable craftsmanship over loud logos. Their collection is a masterclass in foundational pieces that form the core of a sophisticated work wardrobe. From structured totes that hold a laptop and essentials with grace, to silk blouses that drape just so, every item is designed to be a trusted companion in your daily life.
- Upgrade Your Wardrobe With: The Classic Structured Leather Tote. It’s the quintessential work bag—elegant, durable, and perfectly sized. Inside your wardrobe, their Washable Charmeuse Cami is a versatile layering hero under blazers, while the Silk Tee offers a more relaxed but equally polished alternative to a standard button-down.
3. M.M.LaFleur
For the Practical Power-Dresser
M.M.LaFleur was founded with a clear mission: to take the stress out of getting dressed for the modern professional woman. Their approach, which they call "Power Casual," perfectly captures the new era of workwear—polished and authoritative, yet comfortable and practical. They are deeply committed to responsible practices, working with ethical factories and increasingly incorporating recycled and eco-conscious materials. What sets them apart is their obsession with functionality; many of their pieces are wrinkle-resistant, machine-washable, and designed with clever details like adjustable hems.
This is the brand for the woman who needs her clothes to work as hard as she does. The aesthetic is sharp, tailored, and unapologetically professional, but never stuffy. They offer a fantastic range of silhouettes that flatter different body types, and their innovative fabrics mean you can step off a long flight and walk straight into a meeting looking crisp and composed. M.M.LaFleur is less about fashion and more about strategic, high-performance apparel for the ambitious woman.
- Upgrade Your Wardrobe With: The legendary Jardigan. It's their knit-blazer hybrid that offers the structure of a jacket with the comfort of a cardigan. Another must-have is the Foster Pant, a miracle of tailoring that is famously flattering and comes in a variety of high-tech, comfortable fabrics.
4. Amour Vert
For the Eco-Conscious Creative
Amour Vert, which means "Green Love" in French, places environmental stewardship at the very heart of its brand. Their commitment is impressive: for every tee purchased, they plant a tree. They prioritize natural, biodegradable materials like TENCEL™ Modal, which is made from sustainably harvested beechwood trees, and use non-toxic dyes. Their production is localized, with 97% of their garments being cut and sewn in California, ensuring better quality control and a smaller carbon footprint.
Their style is a beautiful blend of Parisian chic and laid-back California ease. While they offer fantastic basics, Amour Vert truly shines with its signature prints and soft, feminine blouses. This is the perfect brand for adding a touch of personality and color to your work attire without sacrificing professionalism. Their pieces are soft, breathable, and incredibly comfortable, making them a joy to wear through a long workday.
- Upgrade Your Wardrobe With: One of their beautiful printed Silk Blouses. They are perfect for tucking into high-waisted trousers or a pencil skirt. Also, explore their collection of TENCEL™ dresses; the Lauda Washable Silk Dress is a versatile piece that can be styled with a blazer for the office or worn on its own for after-work events.
5. Kotn
For the Champion of Ethical Basics
If the foundation of a great work wardrobe is high-quality basics, then Kotn is your go-to. This certified B-Corporation has built its entire business model around a single, remarkable material: authentic Egyptian cotton. They work directly with cotton farming families in the Nile Delta, ensuring fair wages, safe conditions, and investing a portion of their profits back into the community to build schools. Their model is a powerful example of how a company can be both profitable and a force for good.
Kotn's aesthetic is clean, minimalist, and built for layering. They have perfected the essentials: the crisp t-shirt, the slim-fit turtleneck, the simple-yet-elegant dress. The quality of their cotton is palpable; it’s soft, durable, and gets better with every wash. For your 9-to-5, these are the pieces you'll reach for day in and day out to wear under blazers, with tailored trousers, or as a simple, elegant statement on their own.
- Upgrade Your Wardrobe With: Their Essential Crew t-shirt is simply the best—it's the perfect cut and weight. For cooler months, the Mockneck Sweater in one of their beautiful, earthy tones is an indispensable layering piece that adds instant polish to any outfit.
6. Sézane
For the Effortlessly Chic Professional
Sézane embodies that coveted, seemingly effortless Parisian style. But beneath the beautiful aesthetic is a strong commitment to sustainability. As a B-Corp, they are held to high standards of social and environmental performance. They release new collections in limited, responsible quantities to avoid overproduction, and over 75% of the materials used in their collections are eco-friendly, including organic cotton, recycled polyester, and vegetable-tanned leather.
The brand is perfect for injecting a dose of sophisticated charm into your workwear. Sézane is renowned for its exquisite knitwear, romantic blouses with delicate details, and perfectly cut trousers. Their pieces have a timeless quality but always feel current and fresh. They are ideal for a business-casual environment or a creative office where personal style is celebrated. As Goh Ling Yong often advises, building a strong personal brand means finding pieces that make you feel like the best version of yourself, and Sézane excels at this.
- Upgrade Your Wardrobe With: The iconic Gaspard Cardigan. This soft, versatile knit can be worn buttoned up in the front, buttoned up in the back as a sweater, or open as a classic cardigan. Also, look for the Clara Trousers—a high-waisted, wide-leg cut that is universally flattering and supremely elegant.
7. ADAY
For the Modern, Minimalist Multitasker
ADAY is designed for the woman who does it all. Their philosophy centers on creating a "capsule wardrobe of conscious essentials" that are seasonless, versatile, and technically advanced. They believe you can do more with less. Their fabrics are often vegan, recycled, and feature performance qualities like thermoregulation, wrinkle resistance, and even UV protection. They work with solar-powered factories and focus on creating pieces that seamlessly transition between work, travel, and leisure.
The ADAY look is minimalist, architectural, and slightly futuristic. Think clean lines, smart silhouettes, and a neutral color palette that makes mixing and matching a breeze. This brand is the answer for anyone who wants to look sharp and put-together with minimal effort. Their pieces are incredibly low-maintenance (many are machine-washable and air-dry quickly), making them perfect for the busy professional on the go.
- Upgrade Your Wardrobe With: The Something Borrowed Shirt. It’s an oversized, wrinkle-resistant take on the classic button-down that looks amazing tucked in or worn loose. Pair it with the Turn It Up Pants, which are as comfortable as track pants but tailored enough for the boardroom.
8. Reformation
For the Fashion-Forward Sustainability Advocate
Reformation's tagline—"Being naked is the #1 most sustainable option. We're #2."—perfectly captures their ethos: a fun, fashion-forward approach backed by serious environmental commitment. They provide a "RefScale" score for every single garment, calculating its environmental footprint in terms of carbon dioxide, water, and waste. They utilize deadstock fabrics and sustainable materials like TENCEL™ Lyocell, and they are a 100% carbon, water, and waste neutral company.
While often known for their wedding guest dresses, Reformation offers a fantastic selection of work-appropriate pieces for the style-savvy professional. Their collection is perfect for those who work in creative fields or simply want to avoid a cookie-cutter corporate look. You'll find beautifully printed midi dresses, sharp blazers, and chic blouses that make a statement while upholding your values.
- Upgrade Your Wardrobe With: The Veda Blazer. It’s a beautifully tailored piece, often made from deadstock fabric, that can elevate any outfit. Also, their collection of Midi Skirts and Dresses in sophisticated prints can be easily styled for the office with a pair of boots and a simple knit.
9. Patagonia
For the Business-Casual Adventurer
Patagonia might seem like an unconventional choice for workwear, but hear us out. For a smart-casual or creative office environment, their commitment to quality and ethics is unmatched. As one of the original B-Corps, their mission is famously "to save our home planet." They use recycled materials extensively, champion Fair Trade Certified™ sewing, and their Ironclad Guarantee means they'll repair their gear for life, a testament to their anti-disposability ethos.
Beyond the fleece vests, Patagonia produces some incredibly durable and well-designed pieces that are perfect for the daily commute and a relaxed office setting. Their sweaters, organic cotton button-downs, and sturdy trousers offer a blend of outdoor-grade durability and understated, practical style. It’s for the professional who values function and integrity above all else.
- Upgrade Your Wardrobe With: The Recycled Cashmere Crewneck Sweater. It’s incredibly soft, ethically made, and a timeless layering piece. For a more rugged but still office-appropriate look, try their Iron Forge Hemp® Canvas Pants, which are tough yet comfortable and break in beautifully over time.
10. Everlane
For the Seeker of Radical Transparency
Everlane burst onto the scene with a promise of "Radical Transparency," breaking down the costs of their products so consumers could see exactly what they were paying for. While the journey of any brand is complex, their initial mission started a crucial conversation in the industry about ethical production and fair pricing. They partner with some of the best ethical factories around the world and are committed to reducing their carbon footprint and eliminating virgin plastic from their supply chain.
Everlane excels at modern basics—the pieces that form the backbone of a functional wardrobe. Their aesthetic is minimalist, clean, and highly versatile. They are a one-stop-shop for high-quality essentials that look far more expensive than they are. From Italian leather loafers to Grade-A cashmere sweaters and perfectly cut trousers, their pieces are designed to be worn on repeat.
- Upgrade Your Wardrobe With: The Day Glove flat. Made from buttery-soft leather, it molds to your foot and is comfortable enough to wear all day long. Their Way-High Drape Pant is another winner, offering a flowy, elegant silhouette that looks great with a simple tee or a silk blouse.
