What hairstyle goes best with couture? A ponytail, according to Diane Kruger who opted for the surprisingly low-key 'do at two fancy-schmancy Oscar parties.

The actress, 35, attended Chanel's pre-Academy Awards fete in a black strapless ensemble with a feather-accented peplum from the label's Fall 2011 couture collection on Saturday. To show off the luxe look, she pulled her hair into a simple, but elegant, side ponytail and kept her makeup to a minimum.

For the exclusive Vanity Fair bash on Sunday night, Kruger stepped out in a super sexy red Calvin Klein gown with a plunging neckline and exposed lace bra. She complemented the daring design with a sleek, high ponytail that had a small bump in the front.
