The retailer intends to open more than 150 franchise stores across the world over 2014 and 28 Topshop stores in 28 days in the US, extending the expansion of Topshop and Topman's partnership with department stores operator Nordstrom.
Presently, Topshop operates 14 stores in Nordstrom.
The newly proposed 28 stores are slated to open in major US cities such as San Diego, Houston and Washington DC this month.
Arcadia owner Sir Philip Green said the group will open more than 150 franchise stores outside the UK across the company's brands, which include Dorothy Perkins, Miss Selfridge and Burton as well as Topshop and Topman.
The overseas outlets will be opened in Australia, Vietnam, and Canada, with Topshop set to open its first standalone store in New Zealand in 2014.
This expansion of Topshop comes after Philip sold his 25% stake in the brand in December 2012 to a US private equity firm Leonard Green & Partners, a deal that valued Topshop at £2bn.
Meanwhile, Topshop is also in talks to open five more wholly-owned stores in the US. Presently, it has flagship stores in New York, Chicago, Las Vegas and Los Angeles.
Philip added that the company is planning to open Topshop's stores in China, after opening a store in Hong Kong in June.
Arcadia Group is a British multinational retailing company headquartered in London, which owns the high street clothing retailers Burton, Dorothy Perkins, Evans, Miss Selfridge, Topman, Topshop, Wallis and BHS, and the out-of-town chain Outfit, which sells lines from the other group chains.
