As Fashionistas impatiently await the arrivals of September issues to hit newsstands this month, various fashion magazines like Vogue, Elle and InStyle give a sneak peek of the celebrities on their 2011 September cover.

The September issue is arguably the most important issue of the year in fashion magazines, as seen in the documentary "The September Issue" surrounding the making of the 2007 September Vogue.

Editor-in-chief Anna Wintour supposedly was the first editor to place a celebrity on the cover of a magazine, ousting models, in order to boost sales of glossies. Today, most if not all fashion magazines feature a popular celebrity on their cover.

"Anna saw the celebrity thing coming before everyone else did," Vogue's Creative Director Grace Coddington said in The September Issue, citing Wintour as leader of the fashion magazine cover evolution.

As newsstand sales of consumer magazines dropped down to 9.2 percent in the first half of 2011 according to The Wall Street Journal, fashion magazines have all followed suit with the exception of Vogue. Often referred to in popular culture as the bible of fashion magazines, Vogue increased in sales during the first half of the year by 12.7 percent, according to the Huffington Post.

As the Internet continues to stomp its feet on print publications, we wonder if these September covers can help declining fashion magazine sales boost in the second half of the year.

This year, Glee's Dianna Agron gets her first feature cover on Cosmopolitan's September issue. A barely recognizable Anne Hathway graces the cover of Interview and a dolled up sixties-styled Kristen Stewart is featured on the cover of W.
