(Glee's Naya Rivera was the only star rocking a relatively modest knee-length '50's-style vintage swing dress.)
The Kardashian/Jenner sisters (Kylie and Kendall were on hand, too) all went matchy-matchy in buff and black ensembles.
Kim was the only one donning head-to-toe black, opting for a single-sleeved body-hugging minidress -- a silhouette that's become her signature -- by Zuhair Murad with a crystal-encrusted shoulder and Grecian draping.
"Twilight's" Ashley Greene also wore a nude hue -- mixed with pale pink -- on a strapless Valentino dress with delicate black lace detailing on the bodice, paired with Ferragamo heels, a Kilian bag, and jewelry by Stephen Russell.
Other color-less ladies included Selena Gomez, who opted for a white BCBG frock with slit batwing sleeves and Sergio Rossi gladiator heels, and Leighton Meester, who wore a white long-sleeved dress with intricate embroidery by Emilio Pucci paired with Christian Louboutin flower-adorned heels, a Ferragamo minaudiere and Cathy Waterman jewelry.

The most disappointing style of the night came from Katy Perry who traded in her sparkly striped tube dress by Giorgio Armani for a performance costume that looked like it came straight from the mall -- zebra striped leggings, shredded T-shirt, and a pleathery black vest.
Sandra Bullock could have also stepped up her sartorial game, wearing a gray AllSaints T-shirt with horses on it and black leather leggings that looked a tad too casual, as well as a bit dated.
