For the Bryanboys, Tavi Gevinsons and ManRepellers, it's obvious that blogging is a lucrative career.

All have been able to use blogging as a jumping off point into other projects. Gevinson has started her own magazine and launched an acting career. Women's Wear Daily published an article that revealed what bloggers make for appearances. For example, brands may have to pay a blogger between $10,000 and $15,000 for them to appear at an event.

But the really popular bloggers can make $50,000 for an event.

Bryan Grey-Yambao argues that, while $100,000 a year may seem like a lot, it's hard to run a real business on that amount.

The blogger has been offered a six-figure job at a fashion magazine and $75,000 to design three bags from a brand. He turned both down, and he's definitely not the highest-earning blogger.

Many of the bloggers who are making the most money are unknowns. At least, to the world of fashion.

According to Amber Venz, the president of digital management agency RewardStyle, the top five earners on its site are "not who people think they are."

Some bloggers are making as much as $80,000 a month because of affiliate commissions.

Rachel Parcell, a blogger from Utah who runs Pink Peonies, will make at least $960,000 just this year.

Parcell started her blog in 2011, and lives outside of Salt Lake City.

The unassuming blogger started her site to document her first year of marriage.

"I've always had a love for fashion, ask anyone who knew me growing up," she said on her FAQ page. 'I was always the outlandish dresser (sometimes good, sometimes bad). When I got married I started a 'journal blog' to document our first year of marriage. We went on a vacation to Greece in May of '10, when we returned home, I blogged about it and began receiving comments from women I didn't know, asking me to post where I got my outfits. That sparked the idea to begin what is now Pink Peonies!"
