Despite being a major threat to H&M, I honestly think both can co-exist in harmony. They do in the UK and in many other parts of the world. In the U.S., 19 Barney's stores currently carry selections from Topshop, in addition to one New York City Flagship store. In Toronto, you can find some pieces at Jonathan+Olivia in the City's trendy Queen St. West neighbourhood.
One of my fondest memories of visiting London was their availability of Topman stores. I could literally spend an afternoon at their Oxford Circus store perusing their selections.
Canadians just became that much more stylish!
