By now, you probably know that we've spent a lot of time tracking down 30 of the most fabulous, forward-thinking talents under 30 doing their thing in both New York and Los Angeles (that's 60 rising stars in total). You might have even caught a peek at our beautiful Manhattan rooftop bash, celebrating those fantastic NYC creatives, or heard about our awesome backyard shindig thrown in honor of those accomplished Angelenos out West. Well, now we're taking you inside both of those exclusive events to show you the young marvels who attended, all the fun that was had (read: A LOT), and to give you a chance to decide who threw the better party — our L.A. or New York editors. Just take a moment to peruse each image and vote because, in addition to all the bicoastal bragging rights at stake, we'll be throwing a massive Halloween bash in the winning city (with the help of our beloved partner in all of these parties, Stoli) and inviting everyone in town...including you! So, click on the slideshow, place your votes, and may the most party-tastic city win!
