A fake two-storey Primark store that opened in Dubai's Bur Dubai, on Bank Street, may mean legal action for its owners in the UAE.
The store is full of clothes that look just like the real, discount garments from the UK.
Primark is famous for its super-cheap, designer-styled clothes, as well as underwear and home wares.
In a statement to the UAE's National newspaper, the real Primark said: "We are aware that there is a store in Dubai that purports to be part of our group.
"Primark does not operate any stores there and this is not, therefore, a legitimate Primark store. The company is considering its legal options as a matter of urgency."
Primark is one of the biggest retailers in Europe and has 235 stores in the UK, Ireland, Spain, the Netherlands, Germany, Portugal and Belgium.
The National reports local lawyers as saying that, even though it does not have a registered trademark licence in the Middle East, it could face federal fines of fines of Dh10,000 (US$2,722) and up to a year in jail if found guilty of trademark violations.
However it also reports that a knock-off of Canadian discount fashion chain Winners has been operating in Bur Dubai for over a decade.
Clearly there is a need for cheap and cheerful European goods in the UAE - it was announced last week that the real Poundstretcher is to open in Dubai.
