Hayden Panettiere vs. Eva Mendes — Fashion Faceoff

What happens when screen siren Eva Mendes and "Heroes" hottie Hayden Panettiere wear the same silk chiffon Gucci gown almost 10 months apart? Surprisingly, a whole lot of fashion faux pas! Let's break down the two very different ways the ladies modeled the '70s-inspired design, and try to determine just who wore it best.

Hayden, 22, stepped out in the dress for the "Vanities" soiree on February 20 in Hollywood. She added a yellow Laura Merkin clutch and Christian Louboutin snakeskin platforms, then finished her look by pulling back her blond locks.

Eva, who turns 38 on March 5, wore the gown on April 25 at the 2011 Tribeca Film Festival in NYC. The "Training Day" actress accessorized with Van Cleef and Arpels jewels and Jimmy Choo heels, while leaving her dark mane down in waves.

I have no doubt this dress was stunning coming down the runway, but it's obviously tough to pull off on the red carpet! Eva, for example, is gorgeous in the color, but the shape of the gown is too matronly for the "Hitch" star. However, I do like that she's worn her hair down and the fact that her shoes don't distract from the dress. In contrast, Hayden's eye-catching footwear and her bright handbag are a little too much. But what really kills the overall ensemble for me is the "Scream 4" actress' updo, which adds years to her look. Therefore, I declare Eva the winner of this style showdown. Do you agree?
