The chic Kim Kardashian came out on Tuesday night, March 27, to celebrate the 50th anniversary of Valentino and the new Flagship Store opening on Rodeo Drive in Beverly Hill, CA. The 31 year-old opted for a classy dress, all covered up with no curves peeking--what a change from her usual look.

The dress was sleeve-less and patterned in black and white. It covered up her chest in a bateau neckline and sheer shoulders. The bodice was fitted, but the dress featured a full length skirt that went down to her knees and a V shaped back-side.
