The term ‘raincoat’ suggests an expectation of purpose and functionality. This practice-led research project examines how well these expectations are met within the context of urban fashion. Although New Zealand is the focus of the enquiry, the inclusion of an international perspective offers a broader context for considering how such garments have become narratives of identity. The primary site of this research constitutes a collection of rainwear that seeks to address, through practice, concerns the designer has with ‘design integrity’ (or functionality). This functionality may be understood as both physical and social. In the production of the collection, a review of current fashion market trends was undertaken so the work could be developed and positioned as a commercial collaboration. This approach ensured that the design outcome was appropriately located within the market it was seeking to address.
