The 27-year-old Italian, who now lives in Los Angeles, has the broadest reach of any individual fashion blogger on our list, with more than 3 million Instagram followers. She's a global star, as popular in Europe as she is in the U.S. What's more, links from her site drive traffic and conversions, according to many of the brands with whom she has partnered. She was also recently named to an expert panel that will help determine the shortlist for 2015's LVMH Prize. Oh, and she graced the cover of Lucky magazine's February issue along with fellow bloggers Nicole Warne and Zanita Whittington.
