What we wear is often treated as superficial, but if you think of it, it does sit at the intersection of identity, culture, emotion, and decision-making. Few people have explored this space as rigorously as Dr. Carolyn Mair, a cognitive psychologist and fashion business consultant specializing in human behavior and experience.

Dr. Mair is a Chartered Fellow of the British Psychological Society (BPS), an author, researcher, award-winning educator, keynote speaker, and media commentator. She is known for applying behavioral science to the fashion industry and making complex research accessible to wider audiences.

Her book, The Psychology of Fashion (2nd edition), has sold over 12,000 copies and has been translated into six languages. More recently, she has been engaged by cruise lines to deliver talks to international audiences on the neuroscience and psychology of what makes us human.

In 2017, following 20 years in academia, she founded Carolyn Mair Consulting, working across leadership development, business strategy, sustainability, R&D, consumer insights, and well-being. Prior to this, she was a full professor of psychology for fashion at the London College of Fashion, University of the Arts London (UAL), where she established the university's psychology department and created the world’s first MSc programs applying psychology to the fashion industry. The MSc was recognized in 2016 with the BPS award for the UK’s Most Innovative Accredited Psychology Program, and in 2017 she received the BPS Distinguished Contributions to Psychology Education Award. Before joining UAL, she was a full professor of applied cognitive psychology at Southampton Solent University.

After leaving school, she began her career in visual merchandising and graphic design. She later returned to education, earning a BSc (Hons) in applied psychology and computing, followed by an MSc in research methods. She was then funded to complete a PhD in cognitive neuroscience before going on to undertake postdoctoral research in computer science. Bringing together these different disciplines and experiences gives her a distinctive multidisciplinary perspective, shaping the way she shares insights, making them engaging, accessible, and grounded in evidence.

She is driven by a deep curiosity about human behavior: why we think, feel, and act the way we do and how this plays out in everyday contexts. While her academic career began in cognitive psychology, she became increasingly interested in applying psychological science to real-world industries. Fashion, she notes, is a particularly powerful lens, sitting at the intersection of identity, culture, emotion, and decision-making, and importantly, we all wear clothes. Her work is motivated by the potential not only to understand behavior but also to improve it: helping individuals make more informed choices and supporting businesses to operate more ethically, inclusively, and sustainably.

In our conversation, we moved from the psychology of individual style and self-knowledge to the broader questions shaping the future of fashion, from sustainability and consumer responsibility to the deeper changes the industry requires.

Why is it important for individuals to discover their own color, style, and personal clarity, and how does this matter both for themselves and for the brands they interact with?

Psychologically, clothing functions as both a signal to others and a cue to ourselves. What we wear can shape how we think, feel, and behave. Because social influence is so powerful, we often default to external cues such as trends, social media, or perceived expectations, which can create psychological, and sometimes even physical, discomfort and undermine confidence.

In contrast, when our style choices align with our sense of self, we tend to experience greater authenticity, more ease in decision-making, and often enhanced self-esteem. During adolescence, we typically experiment with style as we develop self-knowledge and explore our identity. Over time, we gain a clearer understanding of our preferences, values, and

What makes us who we are, but self-understanding is an ongoing process rather than a fixed endpoint. Some researchers argue we never fully know ourselves, and I agree. However, I also believe that we can come to understand our values and how we want to live and use these as a foundation for the choices we make.

For brands, this matters enormously. Consumers who understand themselves are selective, values-driven, and more loyal. Values and preferences are reciprocally interconnected in the brain. These consumers engage with brands that reflect or reinforce their identity. This shifts the dynamic from persuasion to resonance: brands succeed not by telling people who to be, but by helping them express who they already are.

Many people want to be sustainable, yet also want to feel confident and express themselves through fashion. From a psychological perspective, how can individuals navigate this tension emotionally, mentally, and in their actions?

This tension is a classic example of cognitive dissonance, a psychological phenomenon in which we feel psychological discomfort when we hold two competing motivations, such as wanting to consume fashion for pleasure and identity, while also wanting to behave responsibly. We are driven to reduce the discomfort typically by justifying the behavior (e.g., “this one purchase won’t matter" or “it was such a bargain”) or disengaging from the issue. The challenge is that sustainable choices are often perceived as requiring sacrifice, for example, less choice, less novelty, and less self-expression. The key is reframing, because sustainability does not have to mean restriction or even compromise; it can mean curation and increased value (morally and sustainably). When individuals shift their preferences from quantity to meaning, they often report greater satisfaction, not less. Small behavior changes such as slowing down purchase decisions, prioritizing versatility, exploring secondhand options, or choosing to rent, repair, and restyle what we already own can make a significant difference to how we present ourselves, how we feel, and ultimately, how we act.

Why do we keep buying more than we need, even when we know the consequences?

Overconsumption is driven by powerful psychological mechanisms, including the brain’s reward system (the anticipation of something pleasurable), social comparison (wanting to keep up or belong), and identity construction (using clothing to signal who we are or aspire to be). Fast fashion has been particularly effective at exploiting these mechanisms by creating constant novelty, urgency, and accessibility. However, because we habituate quickly, the emotional payoff is often short-lived, leading to a cycle of repeated consumption. Breaking this cycle requires both individual awareness and systemic change.

At an individual level, recognizing triggers such as boredom, stress, or social comparison can help disrupt automatic behavior. At a systems level, we need environments that make more sustainable choices easier, more attractive, and more socially reinforced.

What real power do consumers have to drive change in fashion, and what might happen if we don’t act consciously in our choices?

Consumers have more power than they often realize. Individual actions may feel insignificant, but collectively they shape norms, demand patterns, and ultimately business models. We see this clearly in areas like resale, rental, and transparency, which have grown because consumer expectations shifted, not because brands led these initiatives. Social norms, driven by consumer behavior, are particularly powerful. When sustainable behavior becomes visible and desirable, adoption accelerates. However, if consumers continue to prioritize speed, price, and novelty without considering consequences, they reinforce the systems that many of them say they want to change. This perpetuates environmental damage, exploitative labor practices, and a cycle of overconsumption that rarely delivers lasting satisfaction. In short, consumers don’t just buy products; their purchasing behavior perpetuates and validates systems; therefore, consumers have the power to change them.

Everyone probably asks you about fashion psychology and what it is, but I’m curious: what is the question you’ve never been asked that you think is most important or relevant to discuss today?

The question I’m rarely asked, but is crucial, is: What role is fashion actually playing in our lives? In regard to consumers, most conversations stay at the level of behavior: what we buy, which trends we follow, and whether something is “sustainable.” But from a psychological perspective, those behaviors are outputs, not causes. What matters more, especially to me, is the function fashion serves: is it supporting identity formation, self-expression, and social belonging, or is it tied up with external validation, social comparison, and emotional regulation?

Fashion can operate as a tool for intrinsic satisfaction, helping us feel coherent, confident, and aligned with our sense of self. But it can also become entangled with extrinsic drivers, where choices are shaped by perceived judgment, status signaling, or the need to manage uncomfortable emotions. Shifting the conversation from consumption to function reframes the issue from limiting behavior to understanding motivation. From that lens, the goal is to engage with fashion in a way that supports psychological well-being, rather than reinforcing cycles of comparison, impulsivity, or dependency.

If you could magically reshape the fashion industry exactly as you think it should be, what would that world look like? What are the most urgent changes needed to get there?

In an ideal scenario, the fashion industry would move from a volume-driven model to a value-driven one. Success would no longer be measured by how much is sold but by how well products serve people and the planet over time. This would include designing for longevity and adaptability, embedding inclusivity from the outset rather than as an afterthought, and making transparency the norm rather than the exception. Importantly, business models would shift towards repair, resale, rental, and circular systems that decouple revenue from constant production. From a psychological perspective, the industry would also take responsibility for the behaviors it currently encourages, such as engineered urgency and overconsumption, towards empowering consumers to make considered, informed choices.

What do you most wish to bring to the world over the next decade through your work in fashion psychology?

Over the next decade, my aim is to continue bridging the gap between psychological science and the fashion industry in ways that are both rigorous and practical. For individuals, I want to help people understand themselves better, how their choices are shaped, and how they can align those choices more closely with their values, identity, and well-being. For businesses, my focus is on embedding behavioral insight into strategy, supporting more ethical decision-making, more inclusive design, and more effective ways of encouraging sustainable behavior. Ultimately, my goal is to contribute to a fashion system that enhances human experience and supports confidence, creativity, and connection rather than one that exploits and compromises people or the planet.

What emerges from Dr. Mair’s work is a clear shift in perspective: fashion is not simply about what we wear, but about how and why we make our choices. From identity and self-expression to habit, emotion, and social influence, our clothing is deeply tied to human behavior.

Her approach reframes fashion from consumption to understanding. Instead of asking what we should buy, the more relevant question becomes what role clothing plays in our lives and whether our choices genuinely support who we are and how we want to live.

This is also where styling, in practice, finds its deeper purpose. Not as a tool to impose trends or aesthetics, but as a way to translate that self-understanding into tangible choices, helping individuals align what they wear with their identity, values, and daily reality.

In that sense, developing a personal style is less about having more and more about making clearer, more conscious decisions, an approach that benefits both the individual and, ultimately, the wider system.

For readers who want to go deeper, Carolyn’s book The Psychology of Fashion (2nd edition) is available from all good book sellers, and she can be followed or contacted through LinkedIn. I have read her book several times and can personally recommend it; it changed the way I perceive style and has been a foundational influence in shaping my own approach to helping clients buy less but better.
