Effortlessly cool is the style of a girl who threw on an outfit from her bedroom floor, walked out the door, and somehow ends up the best-dressed person on the block. Her clothes might be wrinkled and last night's makeup might still be on, and the point is that she couldn't care less. Baggy pants and a baggy t-shirt do most of the work, usually a band tee or something with a funny graphic, sometimes a tank top instead. A blazer or leather jacket goes over the top. The finishing pieces are chic boots and a statement bag.
