The agency has been tasked with raising the profile of the brand following a competitive pitch.
Reiss opened 25 stores and concessions in the UK last year and currently has ten US-based stores. The brand's forthcoming Autumn/Winter 09 collection will aim to capture a broader audience with its younger denim line.
Earlier this year, Relative PR was merged with Paris and London-based MO to create RelativeMO (PRWeek, 07 January 2009). Relative senior partner and founder Justine Fairgrieve heads up the agency alongside MO co-founders Mesh Chhiebber and Olivier Bourgis.
