The 23-year-old had done well in the episode's challenges, winning both the acting telenova assignment and the cheerleading task.
Head judge Elle Macpherson said that Abidde had had an "amazing" week, while Grace Woodward described her acting as "utterly outstanding".
However, Abidde failed to impress the panel and guest judge Tyson Beckford with her photo, which Charley Speed said was "not bad, just not that strong".
"As good as you are at acting, as bad as it is here in this shot," Macpherson said.
Meanwhile, Woodward revealed that Beckford had called the picture "modelling 101" and he added: "You read a lot of magazines, don't you? I could tell when I first saw this. I knew this wasn't you, and I didn't even know you yet."
Macpherson praised Abidde's "remarkable capacity to transform" herself, but during the judges' eliminations, Julien Macdonald suggested: "The personality is stronger than the model."
Ultimately, the panel opted to send Abidde home and save Anastasija Bogatirjova, who was also in the bottom two.
Macpherson explained that the panel had been "divided" and the decision had been "difficult", adding: "As of this point in the competition, it's not, 'Who's the worst girl?' but really, 'Who's the girl that best represents Britain & Ireland's Next Top Model?'"
She added that Abidde had "inspired" the judges, while Macdonald said: "You've changed the way that I look at women, and you're just an amazing person."
Speaking after her elimination, Abidde admitted that she was upset to be leaving the competition, saying: "To go from feeling so confident and doing so well to now be going home, it hurts."
