Fashion Faceoff: Miley Cyrus vs. Rachel McAdams

Jenny Depper

Rachel McAdams and Miley Cyrus have next to nothing in common … except for their similar love for saucy, sexy, little black dresses.

What they wore: A black Saint Laurent by Hedi Slimane silk dress, featuring a peek-a-boo bodice and chain neckline, retailing at $5,990.

When they wore it: The newly single Cyrus struck a high fashion pose in the frock in the October issue of Harper's Bazaar magazine. The 34-year-old actress donned the dress to attend a special screening of "Alles eine Frage der Zeit" on August 10 in Munich, Germany.

How they styled it: The "We Can't Stop" singer kept her look surprisingly low key and punched up the sexy nature of the dress with red lipstick and nail polish and tussled tresses. The "Midnight in Paris" star added a retro flair to the modern dress with a side swept updo, a silver cuff, black Mary Jane heels, and a pale pink pucker.

Judge's scorecard: Miley Cyrus won't stay single for long if she keeps dressing like this. The twerking teen looked gorgeous and age-appropriate in the flirty number and outshined McAdams with her subtle sexiness.
