Most people have had the experience of putting on a specific piece of clothing and feeling different. More confident, more focused, more like a version of themselves they prefer. The temptation is to dismiss this as superficial — as vanity dressed up in psychology.
The research says otherwise.
The scientific study of how clothing affects cognition, behaviour, and self-perception has a name: enclothed cognition. It is a relatively young field, formally named in a 2012 paper by Hajo Adam and Adam Galinsky at Northwestern University, but it draws on decades of earlier research on embodied cognition, identity, and the relationship between physical experience and mental state. The findings are consistent and, if you think about them carefully, not entirely surprising.
What you wear changes how you think. Here is what the research actually shows.
The Lab Coat Experiment — Where It Started
The foundational experiment in enclothed cognition research is elegant in its simplicity. Adam and Galinsky gave participants a white lab coat to wear and then tested their attention and performance on tasks requiring sustained focus. A separate group performed the same tasks without the coat. A third group performed the tasks with the coat present but draped over a chair rather than worn.
The group wearing the coat performed significantly better on attention tasks than either the control group or the group with the coat nearby but unworn.
This is the key finding that defines enclothed cognition as distinct from simple priming: it is not enough to see a symbol. You have to wear it. The physical experience of having the garment on your body is what activates the associated mental schema. The coat on the chair does nothing. The coat on your body changes how you think.
The researchers also varied what participants were told the coat was. When told it was a doctor's coat, performance improved. When told it was a painter's coat — same garment, different framing — the effect disappeared. Both the physical experience and the symbolic meaning are required. Neither alone is sufficient.
What Formal Clothing Does to Abstract Thinking
A 2015 study published in Social Psychological and Personality Science by Michael Slepian and colleagues found that wearing formal clothing — relative to casual clothing — increased abstract thinking and promoted a broader, more conceptual processing style.
Participants dressed formally were more likely to think in terms of big-picture categories rather than specific details. They showed higher scores on measures of "construal level" — the psychological concept that describes whether someone is thinking concretely (focused on immediate, specific details) or abstractly (focused on broader patterns and concepts).
Abstract thinking is associated with creativity, strategic planning, and the ability to identify patterns across different domains. It is the mode of thought associated with leadership, innovation, and long-term decision-making. The research suggests that dressing formally does not just change how others perceive you — it changes the actual mode of cognition you bring to problems.
This has practical implications that go beyond dressing for job interviews. If you are working on a problem that requires creative, strategic thinking, the research suggests that how you dress for that work session may be more relevant than intuition suggests.
Athletic Wear and Performance Identity
The enclothed cognition effect extends to athletic clothing. Research on what has been called "functional athleticwear" shows that wearing clothing associated with athletic performance activates performance-oriented self-schemas — mental representations of oneself as active, capable, and physically engaged.
Participants in one study who wore athletic clothing were more likely to choose active options (taking the stairs, choosing physical activity) in subsequent decisions than those in casual or formal clothing. The clothing had activated a self-concept, and the self-concept influenced behaviour downstream.
This is why the activewear industry's growth is not purely aesthetic. When people buy athletic clothing they intend to exercise in, the clothing itself becomes a commitment device — a physical object that activates the identity of the person who exercises, making it easier to act consistently with that identity.
Getting dressed for the gym is not preparation for the gym. It is, in a measurable psychological sense, the beginning of the gym.
Clothing and Social Identity — What You Signal to Yourself
Most of the conversation about clothing and identity focuses on signalling — what you communicate to other people through what you wear. The enclothed cognition research shifts the focus inward: what does your clothing communicate to you?
The concept of self-signalling — developed by economist Racheli Barkan and others — describes how our own choices function as signals about our identity, values, and commitments, to ourselves as much as to others. When you make a choice that is consistent with a valued identity, you reinforce that identity internally. When you make a choice that contradicts it, there is a cost — a small but measurable form of cognitive dissonance.
Clothing choices are among the most visible and consistent self-signals people make. You get dressed every day. Each choice, however unconscious, contributes to the ongoing internal narrative of who you are. Wearing clothing that expresses a valued aspect of your identity — your sense of humour, your political commitments, your cultural references, your aesthetic sensibility — is not vanity. It is self-coherence. It is the daily practice of being, on the outside, what you are on the inside.
Uniforms, Costumes, and the Transformation Effect
One of the most striking applications of enclothed cognition research is in the study of uniforms and costumes — clothing that explicitly represents a role rather than a personal style.
Police officers report feeling more authoritative in uniform. Surgeons report feeling more precise. Athletes report feeling more competitive in team kit than in practice clothes, even when the physical properties of the clothing are identical. The role encoded in the clothing activates the mental and behavioural schemas associated with that role.
Cosplay sits in an interesting position relative to this research. The act of cosplaying — of wearing the costume of a specific character — involves a deliberate adoption of a costume-as-identity that is more explicit than everyday clothing choices but operates through the same psychological mechanism. Cosplayers who engage seriously with the practice often describe a shift in how they carry themselves, how they interact with others, and how they feel while in costume. The character's confidence, or composure, or physicality, becomes temporarily accessible through the physical act of wearing their clothes.
This is not delusion or escapism in the pejorative sense. It is enclothed cognition operating at its most visible — the deliberate use of clothing to access a mental state that the clothing symbolises.
The Practical Takeaway — Getting Dressed Intentionally
The research points toward a simple practical conclusion: getting dressed is not a neutral act. Every clothing choice activates some schema and suppresses others. The question is not whether your clothing is affecting how you think and behave. It is whether you are making that effect intentional.
Dressing for confidence before a difficult conversation is not irrational. Wearing something that expresses a valued identity on a day when that identity feels uncertain is not shallow. Choosing clothing that signals to yourself who you are trying to be, on a day when being that person feels hard, is one of the most accessible and underutilised psychological tools available.
The lab coat works because it means something and you are wearing it. The same principle applies to everything in your wardrobe.
Wear What You Mean
If clothing is self-signalling — if what you wear communicates to you as much as to anyone else — then the most important question about any garment is not how it looks. It is what it means to you, and what version of yourself it activates when you put it on.
