This is the work of London based colage artist Hormazd Narielwalla.

I’m going to let him do the talking, because this blurb from covers everything beautifully:

He met a Savile Row Tailor, who described the shredding of bespoke paper tailoring patterns of customers who have died. The idea of something so personal and detailed yet ghostly and impermanent led Narielwalla to retrieve a set of patterns, which inspired his first book – Dead Man's Patterns (2008). The first edition was only 100, and collections like the National Art Library, the British Library, and the libraries of the Courtauld Collection acquired copies. 25 other institutions around the UK acquired the artist book for their Special Collections. My work propose a new interpretation of tailoring patterns as interesting abstracted drawings of the human form which have an inherent aesthetic quality that can be used to develop a contemporary art practice. Freed from function they are drawings ahead of their time,anthropomorphic in origin and beautifully abstract in isolation.
