Aurora Fashions has engaged the agency for a six-figure account, to assist with corporate and financial PR.
Fishburn Hedges director Suzanne Morris said: 'The brands are well-known but Aurora is not, so we're helping to raise its profile as the retailing success story that it is.
'We will be building a profile of the management team, while communicating what it is doing in international expansion and how it is becoming a multi-channel retailer.'
Morris is leading a team of four, reporting to Jess Wilks, director, executive office, Aurora. Initially, the brief will be for one year.
Aurora, which also owns Coast, bolstered sales by ten per cent during the Christmas trading period. It posted a five per cent rise in like-for-like sales for the five weeks ending 8 January.
Earlier this month, Aurora, which has 1,586 stores in 48 countries, announced it was outsourcing its distribution and IT functions.
