Dakota Fanning has once again taken our breath away – this time with her appearance at the 70th Venice International Film Festival over the weekend.

The blonde 19-year-old actress stunned in a midnight blue Elie Saab Couture gown which was very apt considering she was there to promote her brand new film Night Moves.

While Dakota opted to go for the fairytale princess factor by opting for a sparkly floor-length dress, there was a certain amount of daring sex appeal to it… just look at that plunging neckline!

The rest of her look was kept simple, with only Rona Pfeiffer and Cathy Waterman rings on her fingers by way of accessories. We think her natural freely-flowing hair stopped the look from looking too prom-like so we’re glad she didn’t go for an intricate up-do on this occasion.
