This New York Fashion Week, we went behind the scenes with 15-year-old fashion blogger Callie Reiff, of Callie's Street Chic, for a week filled with runway shows, front row selfies and wardrobe changes.

Reiff, who is also a model and DJ, has been attending NYFW since the age of 13, and she gave us a sneak peek at what a typical day at NYFW is like. Along with filling us in on what she can't leave her home without and and what exactly goes behind putting together the perfect NYFW outfit, Reiff proved fashion does not have to be expensive. She put together several outfits for us with pieces from H&M and Forever 21, and also shared some of her fashion must-haves which included white hoodies, beanies (for those bad hair days) and Dr. Martens boots.
