Responsible or sustainable fashion is clothing that's more ethical and environmentally friendly. Why? Because of the choices made by everyone involved in using and producing these garments, from the customer to the chief executives leading companies. To understand responsible fashion, we must also consider fast fashion and the social media culture of conspicuous consumption.

Clothes have become so abundant and low-priced thanks to synthetic materials and exploited labor. We can afford to wear items just a few times before disposing of them, and sometimes, we're forced to move on because the clothing quality is so poor. All this amounts to waste, pollution, and unconscionable working conditions.

Compared to the early 2000s, we buy more and keep clothing in our closets for much less time. Not even 1% of clothing is recycled to produce new garments, so old clothing is incinerated or heads to a landfill, and plastic-derived fabrics take up to two centuries to break down and produce methane in the process.

Microplastics from synthetic fabrics enter our water and food with unknown health risks. Approximately 20% of global wastewater is linked to fashion, and the industry uses more energy than aviation and shipping put together. To ensure fast fashion is cheap and quick to reach customers, manufacturers rely on workers in developing countries, including child labor. These laborers work crazy hours in often hazardous conditions and don't earn a living wage for their efforts.

Unfortunately, the onus currently falls on the consumer to find companies making strides in cleaning up their supply chain and design processes. This is difficult when greenwashing is so common. Greenwashing refers to misleading marketing tactics using terms like "sustainable" that aren't regulated. Companies often overstate their eco-friendly initiatives or make claims that are not true. The EU's green claims proposal wants companies to provide verifiable evidence for their green labels, but until laws come into place, customers have to do their research.

Look for credible sustainability certification and audited sustainability reports. Learn about fabrics. For example, vegan leather isn't as green as it sounds, and materials like bamboo may be touted as sustainable when potentially harmful chemical processes are used to soften them. Check out brand websites for evidence of transparency, including scores from reliable third parties. Are the brands using generic photos to relay their ESG efforts? That could be a red flag.

Spend your hard-earned money on higher-quality garments that you will love having in your closet for many years. Well-made clothing can stand the test of time—even if a shirt or pair of trousers seems expensive, its durability and longevity make for a low cost per wear. If you purchase a neutral color that you can wear often and divide the price tag by the number of times you can wear an item, you'll frequently find that high-quality items cost you less in the end.

If you're someone who gets bored with wearing the same clothing for more than a couple of years, you can sell clothes you're tired of on pre-loved marketplaces and thrift stores online and purchase clothes from these stores, too. Never toss your old clothes in the trash when brick-and-mortar charity shops or interested individuals in your community could benefit from them. As for all that quiet luxury you keep hearing about—you can get your hands on it for a fraction of the price in second-hand boutiques. Educate yourself on how to spot the good stuff with better stitching and finishes.

The circular economy keeps materials in repeated use. Purchase only what you have to and outsource the rest—formalwear is only needed a couple of times, after all. Resale and rental companies like PoshMark and the RealReal with circular business models have become popular and are a small step in the right direction, even if their methods need refining.

Less is more, guys. Don't be tempted by those SHEIN overconsumption hauls that give online shoppers dopamine hits. Focus on building a capsule wardrobe and invest in pieces that fit you well and in brands known for their quality—a higher price tag doesn't always mean better quality. Pieces should be versatile so you can easily mix and match. Minimalism means less clutter, which can give you a psychological boost too.

Organic hemp has been used in clothing for centuries because it's suitable for every season and softens when you wash it. Hemp is a low-maintenance plant as well. Organic linen is similar to hemp and is biodegradable and resistant to moths. Regenerative or recycled cotton is even better than organic cotton, and recycled polyester is made from plastic waste, which is great but still releases microplastics.

Look for single-fiber garments which are easier to recycle because they're made from one type of material. Lyocell is a sustainably produced option made from wood pulp, and Tencel is a well-known brand. Avoid nylon, polyester, and acrylic, which are linked to fossil fuels, and regular cotton, which puts too much strain on the environment.
