Sideways Fishtail Hairstyle

From the front, you'd think Emma Stone's low, messy updo was your average chignon. From the back, it's actually a loose fishtail that starts behind Stone's right ear, travels along the back of her head, and ends on the left side of her neck. The key to this romantic style (besides knowing how to fishtail) is the texture, which can be achieved by wrapping small sections around a medium-size curling iron, alternating the direction of the curl as you go.
