Gwyneth Paltrow wowed in a sheer-panel Antonio Berardi gown at the Iron Man 3 premiere in Los Angeles last night.

The actress, who was named the World's Most Beautiful Woman in People magazine on Wednesday, chose a daring evening dress which looked demure from a distance, but featured mesh panels down the sides.

The actress told E! news on the red carpet: "It's very see-through. I just thought it was really beautiful and it sort of has a superhero thing happening."

She wore her peroxide blonde locks loose and straight, while simple but glowing makeup finished off the attention-grabbing red carpet look.
