Topman will expand its flagship store on London Oxford Street to 23,000sq ft later this month.

The extension, which will see the store will see it expand up a floor, is set to open on September 17.

The extended store is modelled on Topman’s New York store, which opened earlier this year.

A new “Red Area” adjacent to the stores’s entrance will showcase new brands and collections and provide styling tips. It will also include new zone called “Area Two One Four, which will house stylist services, a cafe and a barbers.

Topman managing director David Shepherd said: “‘A time has come when we can confidently say that we have outgrown the current trading space. It’s an extremely exciting time for Topman and the new floor will really reflect that.

“We are offering our customer unrivalled product through our own collections as well as some of the most credible and cutting edge menswear labels out there. The new floor will really be a whole new experience – a true menswear destination – I’m confident there will be nothing like it anywhere else on the high street.”
