Yes, models work really hard, traipsing to endless go-sees and 4am call times. But there sure are some good perks--I mean, besides being blessed with impossibly good looks. The models at the top of the heap, many of whom have become friends and muses to designers over the years, are gifted some pretty amazing swag. We chatted with the likes of Karlie Kloss, Jessica Stam, and Cara Delevingne backstage this past New York fashion week about the best freebies they've ever received from a designer. (Hint: Marc Jacobs is very generous.) Prepare to be green with envy.

Models spend a lot of time in hair and makeup chairs at shows and for shoots, and they have access to some of the most talented hair stylists and makeup artists in the world. It stands to reason that they've picked up a few beauty pointers along the way, so this fashion month we decided to ask some of the best models in the business what tricks they've learned. We chatted with Jourdan Dunn, Coco Rocha, Andrej Pejic and many more backstage at shows in New York, Milan, Paris and London. Click through to learn all their beauty secrets.

Nowadays, you needn't be a model to experience all the glitz, glamour (and, okay, uncomfortable shoes) of fashion month. All you need is a good internet connection, a steady roster of model Twitter accounts bookmarked in your browser and some free time. From hanging with A-list stars (ahem, Kanye West) to goofing off backstage with model besties, find out what Coco Rocha, Karlie Kloss, Jourdan Dunn, Anja Rubik and more, were up to during fashion week--straight from the source.

When Anna Wintour referred to relatively little-known model Arizona Muse in her last February's editor's letter as a "gorgeous, smart, grown-up" and compared her to the likes of modeling giants Linda Evangelista and Natalia Vodianova, we knew the modeling world was in for something big. It's been quite the landmark year for Muse. Top campaigns, extensive runway presence, big covers, and now another feather in her cap -- the number one model in Vogue. Hundreds of models are cast every year in the pages of international editions of Vogue, and when we tallied the results of their work it quickly became obvious who came out on top in 2011. Quantity and quality must be accounted for to make the top 10. Not only must a models' appearances be plentiful, but the quality of those appearances must be stellar as well. This includes factors like only-girl editorials, the caliber of photographers they work with and editions they're in, and their number of overall pages. Arizona's scoresheet was predictably well-rounded. She worked with the best photographers, scored the most solo editorials and graced enough pages to fill an entire August issue all on her own (that's about 220 for those of you keeping track). She started the year with a bang by starring in only-girl editorials for Vogue China, Italia, Paris, UK and US, and that was in just one month! It's an unusual feat for a model to skyrocket to the extent Arizona has since she hit the international scene last year, and while we're thrilled for her success, we wonder if it'll stick. While Muse has the novelty (and sometimes the curse) of it-girl status, it remains to be seen whether she'll be blessed with longevity, the true mark of a great and successful model. We are looking forward to what the new year will bring for her. For now, click through for the rest of the top 10.
