Ari Versluis and Ellie Uyttenbroek are a German photographer and profiler, who have spent the last 15 years studying the dress codes of social groups. They have published a book and website featuring their photographs and findings, called Exactitudes (Exact + Attitude).
Members of the same social group are photographed in similar poses. Juxtaposing their similarity with their desire for individuality. Providing "an almost scientific, anthropological record of people's attempts to distinguish themselves from others by assuming a group identity".
