Blake Lively's (a.k.a. Serena van der Woodsen) cascading curls

To get this look, first get some hair clips at a beauty supply store -- the kind made to hold curlers in place.

Step 1: Roll 1-inch sections of hair around a 1-inch curling iron. (Roll bottom-up, like you're putting in a classic curler.) As you finish each curl, re-roll it with your fingers and clip it against your head.
Step 2: When your whole head is curled, clipped and cooled, release.
Step 3: Brush each curl with a Mason Pearson, or boar-bristle brush. "This adds shine, and it will make curls look polished and 'done,'" LeCompte says.
Step 4: Pin hair back behind one ear.
