Ivanka Trump's beleaguered fashion brand has taken another kicking after the bosses of TJ Maxx and Marshalls demanded stores throw out her advertisements and take down her special displays.

Last week workers at the chains - which are both owned by TJX Companies - were told that her products would no longer hold pride of place in the stores.

'Effective immediately, please remove all Ivanka Trump merchandise from features and mix into [other products on the racks]', the note, leaked to The New York Times, read. 'All Ivanka Trump signs should be discarded.'

It's yet another blow for the socialite's business, which has already been dropped entirely by a string of retailers, including luxury chains Nordstrom and Neiman Marcus, as a major anti-Trump boycott continues.

Drawing the line: Ivanka Trump's lines of clothing and shoes have lost their special display stands at sister chains TJ Maxx and Marshalls, and will be mixed in with other brands

TJX Companies has tried to play down the change, saying it often reorganizes its products.

But one worker said that in several years working at the store, she'd never once seen an order demanding that a brand's adverts be thrown in the trash.

And having Ivanka's luxury brand mixed in with other lines will do nothing for her sales.

The store is infamous for is cluttered and disordered racks and bins, where individual lines are lost in piles of other merchandise.

It's so famous for being messy, in fact, that parody site The Onion once joked that it was impossible to tell whether the store was operating normally or in the middle of a closing-down sale.

Doreen Thompson, a spokesperson for TJX Companies played down the significance of the change, telling Racked that the chains would continue to sell the brand.

'We aim to offer a merchandise mix that gives our customers a choice in what they may want to purchase,' she said.

And while she said the company still hosted Ivanka's products 'at this time,' she didn't say whether they would continue to buy them in once stocks were sold out - or, like Nordstrom, drop them completely.

Nordstrom claimed that its decision to ditch Ivanka Trump's line was purely based on the 'steady decline' of sales, and a visit by DailyMail.com to a Nordstrom store did indeed show a number of her products marked down by almost 50 per cent.

But the timing - in the midst of the anti-Trump #GrabYourWallet boycott movement that began in October - may seem suspicious.

It was certainly taken as a shot across Ivanka's bows by Donald Trump himself, who took Nordstrom to task in a tweet on Wednesday.

'My daughter Ivanka has been treated so unfairly by Nordstrom,' he wrote. 'She is a great person - always pushing me to do the right thing! Terrible!'

But it's not just Nordstrom and TJX Company that have given Ivanka the cold shoulder since the boycott began.

Last Friday her brand was dropped by luxury retailer Neiman Marcus, which ditched all of her jewelry and other items from its website, and removed her name from its designer brands A-Z list.

Her products have also been removed from its stores. The company blamed poor sales of the items for their removal.

Department store Belk has followed suit; on Monday all references to Ivanka Trump disappeared from its website - it also said her line failed a regular performance review of her brands.

One company that has openly stated that it was influenced by the #GrabYourWallet campaign is Shoes.com.

In a now-deleted tweet the company told three people - including Shannon Coulter, one of the brains behind the boycott - that their 'voices have been heard.'

'We have removed the products from our website,' it promised.

Nordstrom shares rose by two points in the hours after Donald Trump's furious tweet,The Washington Post noted - unlike the effect previous Trump tweets have had on Lockheed Martin, Toyota and General Motors.

But as Kimberly Whitler, a marketing professor at the University of Virginia, told The Washington Post, Trump has less direct control over them than on government contractor Lockeed Martin, or the US auto industry.

And, she said, consumers might also be getting used to his furious tirades, which are a daily occurrence on his Twitter feed.

'At some point, with the velocity of Trump’s tweets, it's likely that investors may become more "numb" to his tweets and react in a more muted fashion,' she said.
