Last night's Los Premios MTV 2009 Latin America Awards were all about sexy little party dresses and shoes that "walk the walk."

And the style high points were...

Ashley Tisdale in a black, Camilla and Marc Lotus dress. This modern, "bad girl" take on the tutu marks my favorite look of the night.

Kelly Osbourne wearing a short, bell-shaped D & G number. While I love the almost-black plum shade of this dress, I would've preferred to see it paired with nude heels (less matchy-matchy).

Alessandra Ambrosio sporting a partial-lace, embellished Balmain bodice. The tight fit of this dress is a model make.

Nelly Furtado in a studded, Elie Saab sheath. The simplicity of this nude shade helps to balance out the business of the details. The dress shown was just one of three Elie Saab dresses worn by the performer throughout the night.

Audrina Patridge rocking a sequin-clad LBD. Long sleeves and Lanvin thigh-high boots help the mini dress transition to fall.
