Spritz some styling spray into your hair (to give it some guts) and quickly blow-dry, shaking hair out with your fingers so you ramp up the volume.
Take a large-barreled (1.5 inch) curling iron and wrap 2-inch sections of hair.
Take a natural boar-bristle brush and brush through the curls to loosen them into waves. To make this look a little more special/offbeat, add a whimsical headband to shake up a more traditional evening look.
