Here in New York City, each social circle is brimming with the variety of life. Influencers in every field rub elbows at parties, bump shopping bags at boutiques, switch gears and careers so much so that it's hard to keep up. That's why we bring you the Guest List series, where we sit down with the city's coolest residents and discuss why they're making such a splash. From DJs to designers, artists to authors, see who we put in the spotlight in 2013.
