She caught the eye of global superstar Justin Bieber and left a bevy of male admirers in her wake after taking to the Victoria's Secret runway. 

And it wasn't hard to see why, when Hungarian model Barbara Palvin headlined L'Oreal's latest launch in Sydney on Tuesday.

As one of the brand's global ambassadors, the 21-year-old stood alongside Australian face Megan Gale, 39, to unveil L'Oreal's new app Makeup Genius.

Featuring thick straps and a clean, horizontal neckline, the one-piece fell into a slightly loose trouser.

For a subtle pop of colour, Barbara slipped her feet into Jimmy Choo's gold glitter Lance heel. 

Posing alongside Megan, the ladies possessed very different variations of beauty.
