Pregnancy has nothing on the bond between a woman and her heels. And Olivia Wilde  showed no sign of moving to flats when she stepped out for Revlon in a relaxed black design, edgy gold accessories, and strappy block-heel sandals.
And she's not the only star giving us something to admire! Jessica Simpson  knocked us out earlier this week in a yellow sheath at the annual John Varvatos Stuart House Benefit looking her hottest in a bright yellow dress. Add Emma Stone  and Cameron Diaz  to the list, and you'll see why this has already been a very chic week.
