War Boutique plays on parallels with the concept of the 'fashion house' to examine cultural trends, and to experiment with new ways of presenting, distributing and contextualising work. His moniker parodies the concept of the 'fashion house', producing collections inspired by classic imagery and historic conflicts and trends. As one commentator noted, Kevin Leahy "symbolically transforms instruments of war and destruction into constructive items embodying creativity, peace and critical social commentary".
In 2009, Kevin Leahy went on to obtain an MFA in Fine Art from Goldsmiths College. War Boutique has been brought into the public eye once more through his feature in a BBC4 documentary following his graduates of Goldsmith's Art College. The programme followed War Boutique in the last stages of his degree leading up to the final degree show.
