There was an article on Dec 17th in the Guardian reporting from the trial. If she really believed everything was authorised "I was lucky enough to have beautiful and authorised gifts" - then why all the "can't explain/don't remember"?
Some excerpts:
The jury heard that in late August 2010 she flew to New York, stayed at Soho House and shopped at Louis Vuitton in a trip that cost over £5,000, according to credit card statements, Carpenter said. "I am suggesting that is money spent by you, on your own or with a personal friend," said Carpenter. "I don't remember," said Grillo.
On 4 September 2010 she went to Paris for a day, withdrawing €300 (£250) from St Pancras Eurostar terminal and spending £707 in Chanel, Carpenter said. "I can't say yes or no," said Grillo.
Carpenter asked if spending of nearly £5,000 on flights, hotel and at Chanel was personal unauthorised spending. Grillo said she could not remember.
The following month there was a four-day trip to New York costing more than £8,000, Carpenter said. Grillo said she could not explain it.
