From the Opening Night of the Metropolitan Opera to the sweltering hot streets of Los Angeles, stars were out and about on Monday showing off their fab and drab style.

Kerry Washington scored herself the best look of the day, hitting the opening night of Das Rheingold at the MET in a gorgeous Grecian style Marchesa gown, which featured purple embroidered detail.  The leading lady couldn’t have looked more sexy or sophisticated in the off-the-shoulder creation, which was perfectly hued for her skin tone.

Miley Cyrus showed a little too much skin for seventeen, trying to beat the record-breaking heat in Los Angeles.  Her bra-baring lace top, which she paired with uber-tiny cutoff jean shorts and cowboy boots was a little too racy for her underage status!

PHOTOS: Stars Who Are Too Sexy Too Young

Cameron Diaz looked Knight and Day divine at the Tokyo premiere of her film, jazzing up a modest Bottega Veneta turtleneck dress with snazzy and color-happy Jimmy Choo sandals, while Gemma Arterton kept in sexy and simple in a strapless black gown at the NYC screening of Tamara Drewe.
