As Gangnam Style hit maker Psy Oppa says, "Dress classy and dance cheesy." Our style star picks of the week definitely know how to keep it sophisticated and simple, while this week's Fashion Don't (we're looking at you Christina) was just plain cheesy...despite the fact that she doesn't really dance anymore.

Olivia Wilde drove us wild in leather-on-leather! While this look can be hard to pull off, Olivia did it effortlessly by mixing two different tones.

Lauren Conrad
deserves the "crown" for best dressed this week, wearing an adorable polka-dot dress from her own clothing line Paper Crown to a Polo Classic event.

Salma Hayek looked steamy in black and rocked one of our favorite trends by adding a pop of color with a bright red clutch.

Unfortunately, Christina Aguilera hit a low note this week by wearing a psychedelic-patterned purple dress, with matching pink and purple extensions, to the American Music Awards nominations announcement.

See all of these celebs' looks in this week's Red Carpet Rewind video above!
