The film features Hannah Ferguson, the Triumph and Sports Illustrated model, as the main character. She sings about finding "the one" with her friends as they look around at different bras.
A fairy godmother helps the girl find the perfect bra ("the one"). Ferguson is then seen in a changing room, looking in a mirror at her bra as she whispers, "I found it."
Eszter Szijarto, the head of brand marketing at Triumph, said: "It is really important for us to find new ways of bringing to life the bra finding journey so that we continue to inspire customers to go for a bra fitting.
"By transforming our model, Hannah, into a cartoon we are treading new ground and by doing so, we aim to create a compelling visual experience that captures the magical feeling of finding the right bra that transforms your life – ‘the one’."
The spot was created by Stories AG. It was written and directed by Tobias Fueter, and the animation director is Mike Huber. The media planning and buying was handled by Carat.
It will air on TV in the UK, Germany and Italy from 13 April until the middle of May.
Triumph is also running a global competition as part of the campaign. Entrants could win an illustration of themselves in the style of the animated ad. It can be entered through the company’s social media channels.
Fueter, the founder of Stories AG, said: "Triumph is a fantastic brand for which to create an emotional story.
"Women easily identify with animated characters, which explains the success of animated fairy tales all over the world.
"Also, the perfect bra and Prince Charming have a lot in common: almost every woman dreams of finally finding the right one."
