Starting a fashion line with less than £5000 is possible, but standing out in a crowded market is essential. Sustainable clothing is an excellent niche market to consider, given the growing awareness of the environmental impact of fast fashion. This article outlines the top trends in sustainable shopping, including reusable packaging, the rise of resale, buying less and investing in timeless pieces, recycling, and the rental market. There are many success stories in sustainable fashion, including Kent-based Elvis & Kresse and People Tree. Kind Bag is also an inspirational sustainable startup that makes stylish, recycled accessories to fight plastic waste successfully. While conducting business online reduces overheads and expands the customer base, physical stores are still advantageous for sustainability-focused brands. This is because recycled, recyclable, and biodegradable materials are more attractive to buyers with sustainability at the heart of their purchasing decisions, and physical stores allow customers to touch, feel, try-on, and test products.
