Second-hand fashion is no longer a fringe movement – it’s a powerful retail force. Growing at nearly 20% year-on-year, the resale market in the UK alone has surpassed £7 billion, with almost one in four fashion purchases now coming from pre-owned items. Online platforms, which already represent about half of all second-hand sales, are leading this shift as consumers search for affordability, sustainability, and unique finds.

For established retailers, this is both a wake-up call and an exciting opportunity. While sales of new apparel are slowing, the resale market is expected to double by 2029, potentially taking up to 10% of total fashion spending. Brands that adapt now will be better positioned to grow with changing consumer expectations.

Why the Resale Market is Flourishing

Across Europe, second-hand shopping has moved firmly into the mainstream. In markets such as the UK, France, and Poland, around 30% of adults are now engaging in resale, with millennial women leading the way. By 2029, the online resale sector is projected to hit €6–9 billion, driven by a mix of new participants and increasing spend per buyer.

This rapid expansion is reshaping fashion retail. Resale platforms provide consumers with more choice, while also diverting sales from traditional retail channels. Brands that fail to respond risk losing relevance – those that embrace or partner with resale stand to gain.

What’s Driving Consumers to Shop Pre-Loved

Price Matters: Almost half of resale shoppers are motivated by affordability. Many sellers also use these platforms as a way to generate extra income.

Conscious Choices: A growing number of consumers (10–20%) are motivated by sustainability, choosing second-hand to reduce their environmental footprint.

The Thrill of the Hunt: From premium labels at accessible prices to the excitement of finding something unique, 20–30% of shoppers cite the “treasure hunt” factor as part of resale’s appeal.

These motivations show a clear trend: today’s fashion consumer is thoughtful, value-driven, and increasingly open to alternatives beyond first-hand retail.

In Australia, platforms like Treasures Discovered are bringing this global movement to life. Focused on curating quality pre-loved fashion and unique finds, Treasures Discovered makes it easier for shoppers to embrace affordability and sustainability while enjoying the thrill of discovering something special.

As more consumers look for smarter ways to shop, sites like Treasures Discovered highlight the power of second-hand to reshape the future of fashion.

What This Means for First-Hand Brands

The growth of resale is directly impacting new apparel sales. In the UK, roughly one in four fashion units sold is now pre-owned, and this share is only expected to rise. By 2029, second-hand fashion could represent 10% of the total fashion market, setting a new direction for the industry.

Fast-fashion names such as Zara, Primark, and Shein dominate in listing volumes on resale platforms. But it’s the mid-market brands – such as M&S and Next – that face the greatest challenge, as they are among the most resold by volume and therefore most exposed to shifting consumer habits.

For brands, the message is clear: the rise of resale isn’t a passing trend – it’s a structural change in how people shop. Success lies in embracing this evolution, whether by exploring resale partnerships, offering buy-back programs, or finding new ways to highlight sustainability and value.
