Hair How-To: To get Bilson's beach-y waves wrap sections of hair, starting at eye level, around a 1-inch curling iron. For extra fullness, flip hair upside down and mist with hairspray. We're fans of L'Oréal Paris Elnett Satin Hairspray, $14.99.
Makeup Tip: Pair a bright pink lipstick (a sheer formula is easiest to pull off) with flirty, flushed cheeks. Try Clinique Different Lipstick in Raspberry Glace, $14, and Make Up Forever HD Microfinish Blush in Nip Slip, $25.
