The 29-year-old actress has to wear the restrictive piece of clothing for her role in historical movie 'The Favourite', and has said she has a newfound sympathy for the women of the past who had to wear corsets every day, as she was left unable to breathe after just 30 days.

Speaking during an appearance on 'The Graham Norton Show' - which airs on Friday (26.10.18) - Emma said: "Women existed like that for such a long time, which gives you a lot of sympathy for that time period and what they were going through. For the first month, I couldn't breathe and I would smell menthol and it would make me think I was in a wide-open space and could breathe for a moment in time.

"After a month, all my organs shifted - it was gross and if you don't have to, don't do it!"

The 'La La Land' star isn't the only one to have a gruesome corset story to tell either, as Dakota Fanning claimed in July that after wearing the item for seven months whilst filming TV show 'The Alienist', her body "completely changed".

She said: "Seven months; your body completely changes. You can get [the corset] on without even lacing or unlacing. By the end I was just snapping it on, snapping it off. It was like second nature."

Meanwhile, Emma - who stars as Baroness Abigail Masham in 'The Favourite' - recently revealed she was left "shocked" by the history of the British royals during her research for the role.

The movie centres on the court of Queen Anne (played by Olivia Coleman) in the early 18th century as Abigail and her Sarah Churchill, Duchess of Marlborough, played by Rachel Weisz, as they engage in a bitter rivalry to become court favourites.

And Emma couldn't believe how "violent and sexual" royal history can be.

She said: "[We were] mutually shocked. Your royal history wasn't so picture perfect! Henry VIII beheaded his wives. And there were certainly things going on during other reigns that were violent and sexual."
