If you're still unsure what a hipster is, just refer to the vintage dress aficionado Lena Dunham. After writing, directing and starring in the indie film Tiny Furniture, HBO pegged Dunham to create Girls (a series about the very definition of the word), which is set in the hipster capital of the world, Brooklyn, NY. The show, which in many ways is the ying to Sex in the City's yang, has not only catapulted this tattooed actress to the forefront of young Hollywood, but it's also made the culture more visible to the mainstream.
