Billie Eilish was completely unrecognizable as she continued filming the movie adaptation of Sylvia Plath's novel The Bell Jar in Toronto on Tuesday.
Eilish will be making her big screen acting debut playing Esther Greenwood, a 19-year-old college student who falls into depression after taking a magazine internship in New York City in 1953.
On Tuesday, Eilish, 24, looked straight out of another era as she threw herself into the role for another day of filming.
Long gone were her signature baggy clothing and in their place was a costume that transformed Eilish into a young college student from the 1950s.
She wore a blue dress, matching hat, bold red lipstick and curly hairstyle – all of which would have made her unrecognizable even to her most die-hard of fans.
The star was clearly taking the role very seriously.

Eilish, whose character travels from Boston to the Big Apple, appeared studious and focused as she waited for one of New York City's iconic yellow taxis.
Known for wearing loose-fitting T-shirts and trousers, it's a look that would have any Eilish fan doing double takes.
She previously revealed why she chooses to wear unconventionally baggy looks for a pop star – a contrast to hyper-feminine peers like Sabrina Carpenter and Tate McRae.
She told Elle that she experiences 'gender euphoria' when she styles herself in her oversized looks, often consisting of men's apparel.
'I had a really, really toxic relationship with my body. I had a lot of eating issues. I remember putting on, like, a big shirt and the relief that I felt,' she explained.
Listing hip-hop stars Missy Elliott and Tyler, The Creator among her style icons, Eilish said that her 'love for hip-hop culture and wanting to be a man' also influenced her present aesthetic.
'This is the misogyny that we all have within us…which is that I didn't want to be seen as feminine, and therefore weak. It's not right. I've found a good way of not feeling like that.'
