Nazi regalia - it's the new fashion craze that's hit the Western world like a blitzkrieg.
London has maybe changed from the days of Carnaby Street and the Swinging Sixties, but it is still the city that's the global trendsetter. And this season's big seller is that firm favourite the swastika, which so dominated Europe in the ‘30s and ‘40s.
Just hours after the roguish but lovable Prince Harry turned up at a fancy dress party in a Hitler Youth outfit, fascist fashion took off in the high street like a V2 rocket.
And the craze for Third Reich replicas looks set to sweep across the Atlantic and blitz America, finding a market as big as when the swastika fluttered on the fashionable streets of Berlin, Paris, Prague, Warsaw and other European cities.
Demand is so great it's rattling the doors of fashion houses like a stormtrooper's jackboots on a terrified communist's house in occupied Poland!
Young and old, rich and poor are rallying to the new red, white and black flag as what was dubious taste becomes totally tasteful for 2005.
While the Prince Harry ‘Brownshirt' image was first to catch the imagination of Britain's youth, the country rapidly dipped into the full range of Nazi regalia.
Out go baggy jeans and T-shirts and in come jodpurs and smart jackets, burberry baseball caps are being withdrawn in favour of high-fronted black caps, and trainers are now being dumped by the millions as teenagers slip into high-shine jackboots.
Even England's Prime Minister, Tony Blair, has adopted the craze and had a specially-tailored SS uniform made for his close ally and friend, US President George W. Bush, while he has personally opted for the full Benito Mussolini look.
"Prince Harry is undoubtedly the fuhrer when it comes to today's dedicated fascist fashion followers," said Eva Braun, owner of the London boutique, The Final Solution.
"Our mail order business has risen by 200 per cent every day since the Prince unveiled his Brownshirt look and we just can't meet demand for our Maginot line - the SS uniforms worn when Germany invaded France in 1940.
"It really is amazing what the Prince started."
