The move follows project work by the agency for the brand earlier this month around the promotion of a pop-up shop in Regent Street.
It also follows the recent appointment to the fashion brand of design director Gianni Colarossi and previous work with Exposure.
As part of its retainer brief, the agency will be looking to link Colarossi’s AW12 menswear collection with suit-wearers who might otherwise not be associated with the brand to expand its fashion appeal.
Nick Ede, creative director of EdenCancan, said: ‘His work is very diverse and I think we will really show people a great side to Duchamp, which some people may think of as quite floral but in this case is really cutting edge.
‘We’re looking how we can expand the traditional market through artists like Plan B or Professor Green.’
Marc Psarolis, CEO of Duchamp said:'The enthusiasm, passion and professionalism shown by EdenCancan matches perfectly with the values and ambition of our growing brand.'
EdenCancan has also been taken on by beauty business entrepreneur Liz Earle, to look after her personal PR and profiling.
