Sydney-based PR firm Stellar Concepts will manage the campaign and launch events for the opening of H&M's Sydney CBD store later this year.
The company was appointed to the role after reportedly presenting a competitive pitch to the Swedish retailer.
The opening will mark H&M's second Sydney store and will be situated in Pitt St Mall.
Stellar Concepts general manager Hayley Cole believes it's a huge win for the agency.
“This is a truly exciting project to be working on with fashion powerhouse H&M as its retail presence grows in Australia.
“The Glasshouse store will be a spectacular addition to Pitt Street and Stellar is thrilled to be the partner agency for the highly anticipated launch.”
The firm was founded in 1997 and manages accounts across a range of sectors such as fashion, food, travel, wine, retail, beauty and property.
