Calvin Klein is famous for its romps on the beach, Freddie Ljungberg and Jamie Dornan in their pants and THAT 1992 Kate Moss campaign. So what really tipped the advertising watchdog over the edge about FKA Twigs' ad?

The advertising watchdog has been accused of 'double standards' after banning a Calvin Klein advert featuring a semi-naked FKA Twigs while allowing numerous other ads containing similar levels of nudity over the years. 

A poster of British singer-songwriter FKA twigs posing in a shirt was banned by the U.K.'s Advertising Standards Authority for being likely to cause serious offence by objectifying women.

The Calvin Klein poster, released in April, featured the 36-year-old donning a denim shirt drawn halfway around her body, leaving the side of her buttocks and half of one breast exposed, with text reading: 'Calvins or nothing.' 

The ASA did not ban two posters from the same campaign featuring model Kendall Jenner following complaints on the same grounds, finding that they did not focus on her body in a manner that portrayed her as a sexual object and the level of nudity was not beyond that which people would expect for a lingerie ad.

FKA Twig's image bears striking similarities to a Moschino photo shoot with singer Katy Perry, also exposing one side of her body. 

And the ban also comes after The Bear star Jeremy Allen White, 32, showcased his body for a new ad campaign for Calvin Klein, putting his chiseled abs and  biceps on full display while going shirtless for the underwear ad. 

Calvin Klein is famous for its risky ads, having featured big names such as Jamie Dornan and Freddie Ljungberg posing in pants, using an intimate image on the beach to advertise its perfume, and a controversial 1992 photoshoot with Kate Moss - leading critics to ask, why is the FKA Twigs campaign different?

When questioned, the ASA today directed MailOnline to their published ruling which included the claim that in the FKA Twigs advert 'her nudity and facial expression, including a direct gaze and open mouth, gave the image an overall sexual overture. We therefore considered (the ad) was overtly sexual and was not suitable for display in an untargeted medium.' 

Brand and Culture Expert Nick Ede has accused the ASA of 'double standards' - but he said reps for Calvin Klein and the British singer-songwriter will not be unhappy because of the extra exposure.

'There are many adverts that seem to have passed the ASA and have not been banned namely the men's CK campaign with The Bear star Jeremy Allen White revealing his chiseled body and a whole lot more,' he said. 

'The reference to FKA Twiggs being a sexual object rather than someone promoting clothes is nonsense and they need to work out how they can justify Jeremy and not FKA.

'The advert clearly states in their strap line 'Calvins or Nothing!' and in this case she's wearing a Calvin Klein denim shirt. It's not any more sexual or objectifying as recent adverts for Calvin Klein with Kendall Jenner were passed or other brands like Versace, Jean Paul Gaultier and even David Beckham's latest fragrance advert all use the naked body as a sales tool.'

But Mr Ede added: 'Calvin Klein won't be too disappointed with all the controversy this campaign has gathered as once again they are on the tip of everyone tongues but they will have invested a lot of money in buying advertising space and the talent FKA Twigs and photographer and glam team so will be disappointed that people won't see the final campaign.

'The ASA needs to have clear and defined standards that allow brands to temperature check their campaigns. One of the most important things here is consent from the talent and FKA was interviewed and on her socials and has said how proud she was of her campaign which has had support from many celebrities including Michaela Cole who saw it as empowering for women and FKA. 

'There needs to be this added element to allow for this kind of advert to be seen and applauded just as the men's equivalent has been with Jeremy'.

On Wednesday evening, FKA Twigs pushed back on the UK ad agency's ban on her Calvin Klein poster, saying she felt that there were 'double standards' in play leading to the controversial call.

The musical artist, whose full name is Tahliah Debrett Barnett, told her 2.4 million Instagram followers that 'in light of reviewing other campaigns past and current of this nature, i can't help but feel there are some double standards here.'

FKA twigs said that she did 'not see the 'stereotypical sexual object' that they have labelled me,' in reference to ASA's decision to ban the ad after receiving a pair of complaints about the images being 'overly sexualized', offensive and irresponsible, alleging they objectified women and were displayed inappropriately. 

'I see a beautiful strong woman of colour whose incredible body has overcome more pain than you can imagine,' said FKA twigs, who has past been linked to stars such as Robert Pattinson, Shia LaBeouf and Matty Healy. 

Defending the ad, Calvin Klein said it was similar to those it had been releasing in the UK for many years.

Bosses of the fashion brand said FKA twigs, who it described as a 'confident and empowered woman', had collaborated with Calvin Klein to produce the image and had approved it before publication.

FKA twigs wrapped up in comparing herself to past style icons who weren't afraid to take risks.

'So to be clear… i am proud of my physicality and hold the art i create with my vessel to the standards of women like Josephine Baker, Eartha Kitt and Grace Jones who broke down barriers of what it looks like to be empowered and harness a unique embodied sensuality,' she said.

She thanked Calvin Klein and her collaborators who gave her 'a space to express myself exactly how i wanted to.'

FKA twigs wrapped up in saying, 'I will not have my narrative changed.'

Bosses of the fashion brand said FKA twigs, who it described as a 'confident and empowered woman', had collaborated with Calvin Klein to produce the image and had approved it before publication.

It added that all 'conventionally sensitive' body areas were fully covered and the subject was in a natural and neutral position.

The ASA said: 'We considered the image's composition placed viewers' focus on the model's body rather than on the clothing being advertised.

'The ad used nudity and centred on FKA twigs' physical features rather than the clothing, to the extent that it presented her as a stereotypical sexual object. 

We therefore concluded the ad was irresponsible and likely to cause serious offence.'

FKA twigs also featured in a Calvin Klein ad campaign in 2016. 

The ban comes after The Bear star Jeremy Allen White showcased his incredibly toned body for a new ad campaign for Calvin Klein.

Jeremy rocked the iconic brand's briefs for the ad campaign while posing on the top of a building in New York City.

The dashing star was photographed by Mert Alas. The star was also part of a short clip for the brand.

The clip started with Jeremy wearing a white tank top and black shorts walking upstairs to the roof of the building, shedding his clothes down to his underwear to work out. 

He also struck a few poses while shirtless, giving smouldering and mesmerising looks to the camera. 

Jeremy gained 40 pounds of muscle to play the late pro wrestler Kerry Von Erich in The Iron Claw, which was released in December.

He starred alongside Zac Efron, Lily James and Harris Dickinson in The Iron Claw, which was directed by Sean Durkin.

The movie is based on the real life Von Erich brothers - a famed wrestling family that dealt with a lot of tragedy. 

He previously told Esquire how he bulked up for the role, revealing he was 'eating all the time.'

'In the morning I would have waffles, almond butter. In the middle of the day, I was eating turkey patties and avocado all the time. It's really just gross,' he explained to the magazine.

'You're trying to consume as much as you possibly can, and to be honest, you don't feel great. I was training as well, but, I don't know, trying to get that big, it's no way to live,' Jeremy said.

Interestingly enough, in August Jeremy commented on a Calvin Klein ad starring Euphoria's Alexa Demie.

The actress wore a bra and underwear in the smouldering shots for the brand.

Jeremy commented under the ad shared to the brand's Instagram, writing: 'Wow.' 

However, the two stars are not dating. Jeremy is currently dating singer Rosalia.

The Shameless star has two children with ex-wife Addison Timlin: daughters Ezer Billie, four, and Dolores Wild, two.

They married in 2019, with Addison filing for divorce in May 2023. 

Jeremy stars as chef Carmen 'Carmy' Berzatto in The Bear; he previously starred as Phillip 'Lip' Gallagher in Shameless from 2011 until 2021.

MailOnline earlier contacted Calvin Klein and a representative for FKA twigs for comment.
