TOPSHOP OPENS UP(TOWN): Topshop Topman will go big on Nov. 5 when it unveils its largest U.S. flagship and second store in New York, on Fifth Avenue and 49th Street. The company is looking to generate buzz in advance of the opening through giveaways and a New York-centric social media campaign: #UNLOCK5th. To spearhead promotion of the hashtag, the retailer has tapped five “style leaders” from different areas of the city: Julia Restoin Roitfeld, Hailey Baldwin, Kate Foley, Adam Gallagher and Holy Ghost. Using video and photo content, each leader will tout what Topshop and New York City means to them. Launching next week, the campaign will run up until the store’s opening date, when Topshop’s chief executive officer, brand ambassadors and style leaders will officially open the doors to over 40,000 square feet of retail space.
