Red Truth Bobbi Brown Hilary Duff.jpg

If fashion week is about celeb-spotting for you, then the Heart Truth Red Dress Fashion Show is right up your alley. Celebrities model red dresses by the biggest designers in order to raise awareness about heart disease. None other than Bobbi Brown did the makeup (shown above putting finishing touches on Hilary Duff). Brown stuck to a classic smoky eye, luminous bronzers on the face, and either red or sparkling, warm shades of pink and bronze on the lips. She used Bobbi Brown Shimmer Lip Glosses and the brand's new Rich Lip Color.

Sabrina Michals of Bumble and Bumble created the chip updos and loose waves that most stars opted for. For beachy waves, she worked in Bb.Gel and spritzed hair with Surf Spray. Then she used a 1- to 2-inch curling iron to create loose, tousled waves. For the updo hairstyles, she generously applied Spray De Mode to strands before gathering, and set each style with Thickening and Surf Spray to maintain hold.
