Details of the event, which takes place on 24 October, are being kept under wraps, but the St Andrew's Square store is expected to play host to international fashion designers, celebrities and top shoppers in what is being billed an ‘evening of decadence’.
Gemma Hare, the store’s press and marketing manager, said it was a "no brainer" to work with Roselle on the party: "We are delighted to be working with a Scottish agency on this project, especially as we are committed to supporting home grown industry.
"Roselle’s impressive portfolio of clients, excellent track record coupled with an engaging, creative and on-brand pitch made the decision to go with this dynamic agency a no brainer."
Charlotte McIntosh, managing director of Roselle, added: "It is incredibly exciting for Roselle to work with a company as well respected as Harvey Nichols is globally; and it’s a real coup that a local firm was chosen to produce such an event, to celebrate what has become Scotland’s leading fashion destination and an integral part of our Capital.
"Our aim is to create an experience that people will never forget, and we are incredibly excited to reveal all of our hard work on the evening which we are confident will not disappoint."
