SPECIAL EVENT: Save the boho waves for the weekend; big-night hair looks like it took work.  "It's more precise," says Luca Blandi at Oscar Blandi, who has worked with Kate Winslet.

SLEEK & STRAIGHT: Flatiron, pulling each section out so hair doesn't fall flat, says Oscar Blandi, whose clients include Jesica Biel.

GEOMETRIC BUN: Tease the hair underneath before wrapping it into a bun and fastening with bobby pins.  "Don't worry if pieces are sticking out," says Blandi.

TEASED COIF: You can get this teased, romantic 'do without much fuss," says Blandi, who suggests blow-drying with a diffuser to start for body.
