This chapter tentatively explores the role of dress in mental illness and reflects on whether there is space for its routine incorporation in psychotherapy. It begins with an overview of the limited literature on the involvement of dress in psychological disorders like hoarding disorder, social anxiety disorder, and body dysmorphic disorder. Among other things, it highlights the fact that dress may serve as a cue triggering the retrieval of adverse memories and intrusive mental images, in addition to providing a means of camouflage—especially in disorders linked to body image issues. Next, the author reviews evidence on the potential benefits of dress and appearance management in recovery following adversity. Given the scarcity of this evidence and the complexity of mental illness, the author clarifies that dress is unlikely to be a miracle “cure” for mental illness. Nevertheless, it may be beneficial for some patients in some therapeutic contexts, for example as a tool facilitating behavioural activation or the targeting of safety behaviours. The chapter emphasises the need for research investigating the effectiveness of dress in psychotherapy.
