Lauren Conrad's 'do is a foolproof option any time you want to get out of a hairstyling rut. It's a timeless look with lots of sexiness and a little sweetness, too.
Begin by adding some spiral curls with a curling iron, especially around the face. Adding lots of waves and bends will create texture and help make styling easier.
Next, start on one side of the head, behind the ear, and section hair into three large pieces. Either loosely braid the hair in a vertical swath from ear to ear, or just twist the strands together at random. Make sure to use little or no tension during the weaving process.
Once you've worked your way from one side to the other, collect the ends in a ponytail, wrap into a knot or loose bun and pin into place. To finish the style, mist with a medium-hold hairspray.
We've spotted other celebrities with a similar look, including Amber Heard, Abbie Cornish and Zoe Saldana. Check out all the pictures in the Bobby Pinned Updo Lookbook.
