Fashion in the UK: Buying Trends in 2026

Fashion in the UK is changing fast. From social media trends and influencer culture to the growing popularity of second-hand clothing, the way we discover, buy and wear clothes looks very different from even a few years ago.

But behind the trends is an important question: are we buying too many clothes, and what impact is this having?

We’re buying a lot of clothes

The average person in the UK buys around 20 new items of clothing every year. That might not sound like a huge amount, but when multiplied across millions of people, it represents an enormous amount of clothing entering British wardrobes.

Even more surprisingly (according to Oxfam GB's State of Style 2026), around 32% of UK wardrobes are made up of clothes that haven't been worn in the past year.

This raises questions about how often we actually wear the clothes we buy. Are we purchasing things because we genuinely need them, or because a new trend has caught our attention?

Social media is changing what we wear

Social media has become one of the biggest influences on fashion. Around 57% of British consumers say social media influences their clothing purchases. Platforms such as TikTok, Instagram and Pinterest can turn a particular outfit, brand or aesthetic into a trend almost overnight.

Online recommendations are also influencing spontaneous purchases. Around 64% of people say they have bought clothing they weren't originally looking for after seeing it online or on social media.

For younger shoppers, the influence can be even stronger. Among UK 18–24-year-olds, 45% say algorithms are the biggest influence on what they wear or buy.

This means fashion trends aren't just coming from traditional magazines and catwalks anymore. Increasingly, they are being shaped by algorithms and the content appearing on our phones.

Second-hand fashion is growing

At the same time, there is a growing interest in buying clothes that have already been owned.

Second-hand platforms and charity shops have become an important part of the UK fashion market. Apps and websites that make it easy to buy and sell pre-loved clothing have also helped make second-hand shopping more convenient and mainstream.

Research has found that 63% of UK consumers planned to buy at least some second-hand clothing, while 41% said they were buying and wearing more second-hand clothing than they had two years previously.

For many shoppers, buying second-hand can offer a way to find unique pieces, spend less money and extend the life of existing clothing.

The environmental side of fashion

Our shopping habits also have an environmental cost.

Clothing requires significant amounts of water, energy and raw materials to produce. Oxfam estimates that the clothes bought by people in Britain have a water footprint of around 8 billion cubic metres.

The problem becomes even more significant when clothes are bought but rarely worn.

If nearly one-third of wardrobes are sitting unused, then a large amount of the resources used to manufacture those clothes has effectively gone into products that aren't being enjoyed.

So, what does the future look like?

The UK fashion industry is at an interesting point. On one side, social media is encouraging people to discover new trends and buy more frequently. On the other, growing interest in second-hand fashion is encouraging people to reuse clothing and think more carefully about what they purchase.

Perhaps the biggest change isn't about what we wear, but how we think about our clothes.

Buying fewer pieces, wearing them for longer, repairing damaged items and choosing second-hand clothing can all help make our wardrobes more sustainable without giving up our personal style.

Fashion will always change. But in 2026, the biggest trend may be becoming more conscious about the clothes we already own.

After all, the most sustainable item in your wardrobe is often the one you already have.
