Blake Lively's Cannes 2014 Dress Turns Heads With Thigh-High Slit

Leave it to Blake Lively to steal attention away the movies at Cannes 2014!

The former "Gossip Girl" actress attended the festival's opening night premiere "Grace of Monaco" on Wednesday looking fabulous in a sexy Gucci Premiere dress.

The head-turning accessory? Blake's legs, natch, which were flaunted in all their toned glory thanks to a thigh-high slit—a trend that was popular at the 2013 Cannes Film Festival.

It wasn't just the 26-year-old's legs that got us excited either; the stunning bordeaux silk-chiffon gown also featured a cool geometric neckline, a sexy open back and pleats, which probably looked amazing when the wind swept threw it.

Blake also set the bar high with her hair and makeup: a smoky eye, light pink lips and a sleek ponytail kept the look youthful and fresh.

We just wish that Blake's hunky hubby Ryan Reynolds could have joined her on the red carpet!
