Young heiresses Marta Ortega Perez, of Zara, and Topshop's Chloe Green are both being groomed by their fathers to inherit billion-dollar global fashion empires, potentially propelling them into the ranks of the world's richest women.
The athletic and elegant Marta, 27, started work at her father's company Zara, stocking shelves and folding clothes in the Spanish company's London and Barcelona stores.
Her 72-year-old father Amancio Ortega net worth $31 billion is the richest man in Spain and the seventh richest person in the world, according to Forbes.
Marta stands to inherit his fashion giant Inditex's 5221 shops in 80 countries around the world, operating under brand names including Zara, Massimo Dutti, Pull & Bear and Bershka.
The group has 92,000 employees and a $16,874 million turnover last year.
The company also expanded into Australia for the first time, opening a Zara store in Melbourne this year.
Marta's inheritance also includes a massive luxury real estate portfolio, including commercial office blocks in Miami, New York, Lisbon, London, Moscow, Rome, Madrid, Barcelona and Paris; a horse-jumping circuit her father built for her, a stake in a Spanish football team and interests in gas, tourism and banks.
It is a fortune worth 24 times more than Paris Hilton's, according to Vanity Fair.
But unlike Hilton, the university-educated Marta is a mystery to the press.
"Discreet and inaccessible, she doesn't concede interviews," Spanish society magazine Vanitatis said.
"She only has eyes for her family, her boyfriend, horses and the family firm which, perhaps very shortly, will be more hers than ever."
Co-workers at the Zara branch in London's Chelsea, where Marta worked in 2007, recalled a shy girl.
"Sometimes she doesn't even look up from the ground," a former co-worker told Spanish newspaper El Correo.
"One day, when I didn't know who she was, I looked and saw a really expensive Rolex watch on her wrist.
"In Zara, we can all wear the latest fashion items but not a watch like that.
Ortega, the son of a railway worker, made dressing gowns in his living room before opening his first shop in 1975.
He handed the direction of Inditex to his number two, Pablo Isla, 46, when he stepped down as president of Inditex at the start of this year.
Marta, who has worked in the company's offices in Paris and Asia, will be handed control from Isla when she feels ready, industry analysts predicted.
Marta is believed to be working in the company's marketing department and is due to marry show jumper Sergio Alvarez Moya in Spain in February in a Zara-made wedding dress.
"You couldn't say Marta was a pupil who got top marks at school but like her father, she always had a great deal of will and a strong work ethic," a family friend told El Pais.
"She's also a very sensible person and that can make her appear older than she is."
Marta's father is adamant his daughter stays out of the spotlight, telling reporters in 2008: "Who knows what the future holds? What I don't want is the newspapers talking about her. I want the press to leave her alone so she can learn and work and we'll see what she can do in the future."
