Topshop is extending its partnership with US retailer Nordstrom, as it plans to more than double the number of concessions it has in its stores.

The expansion, which comes a year after the partnership launched, will open an extra 28 Topshop concessions and eight Topman departments across the US from September.

The new phase of the deal will increase the total number of Nordstrom stores with Topshop concessions to 42 and the total number of Topman concessions to 18.

It will take the UK fashion retailer to key markets such as Dallas, Houston, Minneapolis, San Diego, Washington D.C., Southern and Northern California, South Florida, and downtown locations in Chicago and Seattle.

In addition, Nordstrom plans to completely refresh its in-store designs for the Topshop and Topman departments. The two retailers will also launch a national marketing campaign together.

Sir Philip Green, owner of Topshop and Topman’s parent company Arcadia, said: “The first nine months have been a steep learning curve for us all, and it has been great to work with Pete [Nordstrom, executive vice president and president of merchandising at Nordstrom] and his team on providing the Nordstrom customers with the very best of what we deliver as great British fashion brands.

“I always believed that Nordstrom’s multichannel presence was the decisive factor in partnering with them in the USA, and we are looking forward to the further expansion across so many great cities, and refining our presence within their stores and online. Hopefully there will be even more to come.”

Nordstrom is Topshop and Topman’s main retail partner in the US however both Arcadia-owned brands have been expanding their own store portfolio with flagships open in New York, Chicago, Las Vegas and Los Angeles.

Pete Nordstrom said: “We are very pleased with our Topshop Topman partnership and excited to expand and grow together.  Through this collaboration, we hoped to attract new customers to both our women’s and men’s apparel businesses and to learn to create newness and excitement in our stores and online. Through a lot of hard work and mutual effort, we have been able to measurably improve on these fronts. “
