Beauty Secrets From the Most Powerful Women on the Runway

The role model: Shannon Schuyler, principal corporate responsibility leader at PriceWaterhouseCoopers

Everyday makeup essential: For the office, Schuyler subscribes to a strict signature look: black clothes, superstraight strands, and five-inch heels. So strutting the runway in a purple frock was a foreign experience, but she looked cool and confident.

Deskside beauty must have: Schuyler told us she keeps many tubes of lip gloss in her desk drawer. "With lip gloss and a comb, I can make anything happen," she said.

Best advice (ever): "Fake it until you make it."
