What is Earth Day?
Earth Day is an annual awareness day, held on the 22nd of April, that brings sustainability and global efforts to reduce climate change into focus. Each year, the organisers of Earth Day highlight a particular theme, issue, or message that sits at the core of their campaign.
This year’s Earth Day theme centres around stewardship. While global legislation and political interest in climate change continue to shift, the movement towards a less environmentally damaging way of living is still being driven by everyday people making small, conscious changes. This theme places responsibility on all of us and reinforces that these small actions matter, especially at a time when greenwashing and unrealistic sustainability targets are increasingly questioned.
There are many simple changes you can make to live more sustainably, but in this blog we are focusing specifically on sustainable fashion and how the clothes you buy, wear, and care for can have a real impact.
Before we begin, we’ve also included some helpful Earth Day resources below that share additional easy sustainability tips you can apply to your everyday life.

Does What We Wear Really Affect the Environment?
The short answer is yes.
The fashion industry is responsible for around 10% of global carbon emissions, which is more than international flights and maritime shipping combined. Beyond emissions, the production of clothing is highly water and energy intensive. Each year, 92 million tonnes of textiles end up in landfill, with a significant portion being clothing. That equates to a bin lorry full of used clothing being tipped into landfill every second.
These statistics can feel overwhelming. However, understanding the scale of the issue can also be a powerful motivator.
Positive environmental change does not require completely overhauling your lifestyle. Instead, it comes from small, consistent changes to how you shop, care for, and wear your clothes. With that in mind, here are five simple ways to make your wardrobe more aligned with sustainable fashion this Earth Day.
1. Choose Second Hand Clothes Over Brand New
As an online second hand shop, this one will not come as a surprise. Choosing second hand clothes over brand new is one of the most impactful changes you can make.
This does not mean replacing your entire wardrobe overnight. In the spirit of Earth Day, focus on small, manageable changes. The next time you are looking to buy something new, whether for a specific occasion or to fill a gap in your wardrobe, consider choosing second hand first.
If you feel sceptical about second hand clothes, you are not alone. Sunshine Thrift’s founder Erin once felt the same way. Over time, she transitioned to buying 100% of her clothing second hand and today, over 50% of Sunshine Thrift’s first-time customers are choosing second hand for the first time.
By choosing second hand, you reduce demand for new production, which requires significant water, energy, and CO₂ emissions. You are also extending the life of clothing that might otherwise end up in landfill.

2. Wash Your Clothes Less
It is estimated that up to 700,000 microfibres can be released into water systems in a single wash, largely due to synthetic materials like polyester and nylon.
Washing your clothes less frequently reduces the number of microplastics entering waterways. It also lowers energy usage and limits the release of chemicals from laundry detergents.
This does not mean avoiding washing altogether. Instead, be more intentional. If you currently wash items after every wear, take a moment to consider whether they actually need it. Washing should be reserved for removing visible dirt, stains, or odours, rather than simply freshening up an item.
Less washing is better for both the environment and the longevity of your clothes. We all want to do less laundry, it’s a thankless task and now we’re telling you it also has a positive impact on the environment, it is a win win!
3. Know How to Care for Your Clothes
Understanding how to properly care for your clothes is essential for extending their lifespan. From washing and drying to ironing, small mistakes can lead to damage that shortens the life of a garment. Let’s face it, if you have accidently shrunk an item in the wash then you’re unlikely to wear that item again.
The simplest way to avoid this is by following the care label. These labels provide clear instructions on how to wash, dry, and iron each item correctly, helping you avoid common issues like shrinking or fabric damage.
Taking the time to care for your clothes properly means you will keep them in your wardrobe for longer, reducing the need to replace them and supporting a more sustainable fashion approach.

4. Repair Before You Replace
Making your wardrobe more sustainable often comes down to how you maintain what you already own.
Clothes are frequently discarded due to small, fixable issues such as missing buttons, minor tears, or changes in fit. Learning basic repair skills can significantly extend the life of your clothing.
There are now countless online tutorials that show how to make simple adjustments, from shortening hems to improving fit. These small changes can make a big difference in how often you wear an item.
Alternatively, you can use a local seamstress for more complex alterations. Searching for “clothes alterations near me” will help you find services that suit your needs and budget.
5. Build a Smaller, More Versatile Wardrobe
Global clothing production has doubled since 2000. At the same time, we are wearing our clothes less, driven in part by fast-moving trends and social media.
Micro-trends which circulate social media and appear in a flash on fast fashion websites are often gone before they’ve even taken hold and that’s why they are referred to as “micro” they are short-lived moments in the fashion world that encourages us to buy more clothes because we want to have the latest styles when in reality, trends are simply recycled from previous trends. In contrast, sustainable fashion focuses on longevity and personal style rather than short-term trends.
Building a smaller, more versatile wardrobe means choosing pieces that can be styled in multiple ways. It is not about owning more, but about making better use of what you already have.
Second hand clothes naturally support this shift by moving away from trend-driven consumption and allowing you to develop a more individual style.
At the same time, avoid overconsuming second hand clothing. Focus on quality over quantity, and consider natural fibres such as wool and linen, which can last longer when cared for properly.
Final Thoughts
This Earth Day, sustainable fashion does not have to mean a complete wardrobe overhaul. Small, intentional changes, from choosing second hand clothes to washing less and caring for what you already own, can have a meaningful impact over time.
By making more conscious decisions about how you shop and wear your clothes, you are contributing to a more sustainable future, one outfit at a time.
