Hajiyeva's London home is one minute's walk from Harrods, where she spent 16 million pounds in a decade, sometimes splashing out tens of thousands of pounds a week, according to prosecutors.
Lawyers for Mrs Hajiyeva said in a statement: "The decision of the High Court upholding the grant of an Unexplained Wealth Order against Zamira Hajiyeva does not and should not be taken to imply any wrong-doing, whether on her part or that of her husband".
He was sentenced to 15 years in jail in his home country in 2016 for fraud and embezzlement.
The National Crime Agency is seeking two UWOs against Hajiyeva - one regarding the £11.5m Knightsbridge property and another relating to a golf club near Ascot built on land owned by a company connected to her.
Zamira Hajiyeva, the wife of a jailed banker from Azerbaijan, is being asked to explain her "unexplained wealth" thanks to a new anti-corruption enforcement scheme created to target organized crime figures and others with foreign government ties. If she's unable to do that, she risks having the assets seized.
Mrs Hajiyeva has made clear her intention to engage fully in the judicial process, and will present her case to the court as appropriate through her lawyers. Following his conviction at a court in Baku, he has been ordered to pay back some $39 million. On another visit to the store, she spent £100,000 on jewellery from Cartier.
FOR years, banker's wife Zamira Hajiyeva indulged her $7400-a-day shopping addiction.
She also travelled the world in a Gulfstream private jet, drinking the finest wines and wearing expensive jewellery.
Duncan Hames, director of policy at Transparency International UK, said: "We are delighted that this first case is progressing in court, underlining the effectiveness of Unexplained Wealth Orders in targeting suspicious wealth".
Now, UK authorities can at will demand to know the providence of that wealth.
The failure of her attempt to throw out the case in the courts last week was hailed as a significant victory for the authorities who have vowed to expand the use of the tactic.
The Azeri finance ministry said about $3 billion could have been misappropriated by Hajiyev, who denied the charges.
"Unexplained wealth orders have the potential to significantly reduce the appeal of the United Kingdom as a destination for illicit income".
'The NCA's case is that the UWO is part of an investigative process, not a criminal procedure, and it does not involve the finding of any criminal offence.
Asked who would then have a right to claim that wealth, he said: "Ultimately, that becomes a political and global issue".
Britain's National Crime Agency (NCA), which is responsible for tackling worldwide corruption, has said that £90 billion is likely to be a significant underestimate of the sums of corrupt and criminal cash flowing through Britain every year.
But the National Crime Agency told the court that Mr Hajiyev had been a state employee between 1993 and 2015 - and as an official he would not have had the means to amass the wealth investigators have traced.
