Stunt was born in London as the younger daughter of Croatian former Armani model Slavica and English Formula One billionaire Bernie Ecclestone.
She attended Trevor-Roberts School, then Francis Holland School, a girls" school, in London.
She has an older sister, Tamara Jane, and an older paternal half-sister, Deborah. She contracted viral meningitis at the age of 14, and told the media that it "changed her life forever". She said "I no longer take my health for granted.
I’m now a health freak and a hypochondriac.
I’m obsessed with cleanliness, I eat healthily and take my vitamins." She has since become an ambassador for the Meningitis Trust. Growing up, she wanted to be a fashion designer.
She decided to make menswear because it is a "bigger niche" and because "womenswear was too saturated". At the age of 19, she created the menswear label FORM, which was sold into retailers including Harrods from October 2008.
In April 2009 it was announced that Petra had signed a contract with the Croatian clothing manufacturer Siscia.
After she reportedly grew "tired of the grind of having to oversee the range", Form collapsed into administration 14 months after start-up, before being liquidated. She launched an accessories line called Stark in September 2011.
