Oct. 10, 2013 -- It's a man's world, except in the world of making money as a fashion model. According to a new ranking from Forbes magazine, male models are still making a fraction in annual salary when compared to their female counterparts.
Forbes magazine, which tracks the wealth of celebrities, politicians and other influential figures, this week released its list of the world's highest-paid male models. According to the report, the 10 top-earning male models raked in a combined total of $8 million from September 2012 to September 2013 -- about one-tenth of the $83 million the 10 top-earning female models earned during that time.
"I'm not going to be complaining about not making $42 million. ... At the end of the day I'm very, very blessed with what I do," O'Pry said. "I don't have to wear high heels and I don't have to wear bikinis, so I mean, more power to the ladies. I'm very happy with my career."
So why do female fashion models at the top of the industry make more than the guys?
Larry D. Woodard, president and CEO of Graham Stanley Advertising and advertising columnist for ABC News, said the reasons are similar to why men's sports is a much larger industry than women's sports.
The men's clothing industry rakes in roughly $400 billion worldwide, but the women's clothing industry worldwide is worth about $621 billion. Female models at the top of the fashion industry have multi-million dollar contracts whereas the men largely are hired for photo shoots, Woodard said.
"Women are at the top-tier professional level when it comes to doing fashion," he said. "It's the only place where women outpace men to the degree that they do."
So the reason Gisele is a household name, but not Sean O'Pry, Woodard said, is because of sheer star power within the industry where women reign.
For male models, attaining supermodel status has been challenging for years, something David Gandy also knows first hand.
"It's an accolade to be a female supermodel or to be a female model," Gandy told "Nightline" in a May interview. "They get paid an incredible amount of money, and they get a lot of coverage and people know their names and guys never did that. They did well but they never said they were models."
Gandy said modeling was difficult for him at first. He started off doing catalog shoots at a time when even male models were expected to be ultra-thin and look almost feminine.
Gandy is arguably one of the most successful male models ever, but he was a bit modest about that "supermodel" title.
"I would sort of just rather be called at the top of the game," Gandy said.
