The “Signature” project is the result of several years of study and research in the field of interdisciplinary artistic fields and phenomenology of contemporary fashion, identity, body as a means in fashion and performative arts, and the post-human condition of the body in performance. In contemporary fashion, the clothing item is morphed into a completely new identity. The real body is transformed by clothes, as well as by other forms (prosthetics, plastic surgery), called human extensions. The evolution of the body and clothes enshrining it represents a spectre of methods, theories and styles in line with every author presented in the “Signature” project. For them, the body should be in harmony with its inner and outer surrounding, since it has a need to intervene and change its nature. We live in a hyper-consumerist society in which everything is reduced to recycled, revitalised images of past historical styles. It all becomes personal styles and yet it still represents in our “spectacle” society. At the Signature exhibition of the Arts Association and Lidija Fistrek as a author, held at the Technical Museum in Zagreb in 2013 and 2016 at the Design Week in Zagreb, four Croatian fashion designers’, performance artist’s, sculptures, music producers works were presented. To these designers, clothing represents a medium, which enters visually into our consciousness and becomes significant as we communicate in nonverbal manners. The approach to clothing and bodies as mediums vividly shows how each author leaves his/her recognisable signature. The body itself, and its personal lifestyle-reflecting appearance, is already visually pre-construed. It needs to dress, to change styles, to intervene and redesign its own „nature” according to changes in the inner and outer environment. Fashion designers use the body surface in various ways as a territory for inscription, which erases in a rather appealing way the boundaries of belonging and offers an opportunity to leave a personal signature mark on their original work.
