Last night, Sophia Bush hosted the 2012 New Garde Los Angeles cocktail event to support I AM THAT GIRL — sponsored by GenArt and Ciroc Vodka, at Petit Ermitage in West Hollywood.

The 29-year-old “One Tree Hill” actress added a pinch of “spring fever” to a nearly all dark look with a pale green v-neck “Abby” dress — with a black mesh insets at the neck and hips, from the Fall 2012 collection by ELKIN.

She layered on a black drape blazer before topping off the outfit with a gorgeous pair of shoes. Sophia is wearing black and silver glittered open toe ankle booties from the Fall 2011 collection by Miu Miu.

Who couldn’t fall in love with these shoes?

With a pin-straight mane — Soph finished her look with a ELKIN bag, multiple rings and a punchy pink pout.

I wish there were some photos sans-jacket to get the full effect of the dress.

The two-hour series finale “One Tree Hill” event airs next Wednesday, April 4th at 8pm on The CW.
