It was all about the itsy-bitsy minidress at the 2010 Teen Choice Awards, where young starlets showed off their enviable gams thanks to a variety of thigh-baring dresses.

(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.

Brightening things up a bit were Emma Roberts -- in a very fashion-forward strapless lime green dress, black booties, raven colored locks and jewelry by Kara Ackerman and Cheryl Greenspoon , Kristen Bell in tomato red Stella McCartney, Hillary Duff in an aqua foam-hued Herve Leger bandage dress, Lea Michele in a Naeem Khan dress with bright green leaf-shape beading and Lorraine Schwartz jewels, and Megan Fox, who went for a fresh and youthful approach, ditching a dress in favor of a silver sequined miniskirt and bold-patterned blue and white blouse, paired with a diamond elephant ring by Ofira.

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.
