The Ivanka Trump brand had its best ever month in February, despite being dropped by Nordstrom and other national retailers for poor sales.

In an interview with Refinery 29, company president Abigail Klem said: 'Since the beginning of February, they were some of the best performing weeks in the history of the brand.

'For several different retailers Ivanka Trump was a top performer online, and in some of the categories it was the [brand’s] best performance ever.'

On Amazon, Ivanka has had the top selling fragrance for the past two weeks, new stock is frequently being added to her Zappos page, and on the London-based e-commerce startup Lyst has Ivanka as the eleventh best seller on the site for the month of February.

That represents an increase of 346% from January, when the brand ranked at 550 on the site.

'We actually feel super optimistic because, I think, one, a lot of people support Ivanka, even across both political parties,' said Klem, who is a registered Democrat.

'And then I think a lot of other people feel like, Oh, I didn't know Ivanka had a shoe line. Oh, I didn't know she had a handbag line. And they're buying it.'

There are no numbers however on in-store purchases of Ivanka brand merchandise, which is still carried by Macy's, Bloomingdales and Dillard's.

Over at Lyst meanwhile, shoes sold the best of Ivanka's goods followed by dresses.

February was a roller coaster month for the brand, from which Ivanka stepped down in January one week before she and her family moved to Washington DC.

It all began when President Trump lashed out at Nordstrom for dumping his daughter's clothing line.

'My daughter Ivanka has been treated so unfairly by Nordstrom,' the president wrote on Twitter last month. 'She is a great person – always pushing me to do the right thing! Terrible!'.

White House Press Secretary Sean Spicer then defended President Trump's comment later in the day, saying that he was responding to 'an attack on his daughter.'

Spicer also implied that the Seattle-based retailer made the decision to drop Ivanka's line because they did not agree with President Trump's ban on immigrants from seven Muslim-majority nations entering the country.

But Nordstrom revealed in a statement to DailyMail.com at the time that Ivanka was personally told about its decision in early January - weeks before the travel ban.

'To reiterate what we’ve already shared when asked, we made this decision based on performance,' read the statement. 'Over the past year, and particularly in the last half of 2016, sales of the brand have steadily declined to the point where it didn’t make good business sense for us to continue with the line for now.'

The statement went on to read: 'We've had a great relationship with the Ivanka Trump team. We’ve had open conversations with them over the past year to share what we've seen and Ivanka was personally informed of our decision in early January.'

Spicer meanwhile justified Trump's tweet, saying: 'He has every right to stand up for his family and applaud their business activities, their success.'

'So, look, when it comes to his family I think he's been very clear how proud he is of what they do and what they've accomplished. And for someone to take out their concern with his policies on a family member of his is just, is not acceptable. And the president has every right, as a father, to stand up for them.'

Spicer was later asked how Ivanka could be targeted seeing as she made the decision to step down from her eponymous fashion company last month, just before moving to Washington DC.

'I think there's clearly a targeting of her brand, and it's her name still out there. So while she's not directly running the company, it's still her name on it,' said Spicer.

'And there's clearly efforts that – to undermine that name based on her father's positions on particular policies, that he's taken.'

Spicer went on to state: 'This is a direct attack on his policies and her name. And so that – there's clearly an attempt for him to stand up for her, because she is being maligned, because they have a problem with his policies.'

The following day things took another turn when Kellyanne Conway promoted the brand during a television appearance.

She was later counselled after that move, which is an ethics violation.

White House lawyers then concluded that 'Ms. Conway acted inadvertently and is highly unlikely to do so again.'
