Scarlett Johansson Tries a Braided Hairstyle for The Avengers Premiere in London

Scarlett Johansson traded her signature bouffant up 'do in favour of a more girly plaited version for last night's The Avengers premiere in London. The blonde beauty teamed her Prada dress with a crown-style braid and megawatt smile for her turn to promote the film in the UK. It's quite a departure from her Black Widow character's red bob, but it's the perfect example of red carpet glamour done with a feminine twist that we've come to expect from the Vogue cover star. Step inside to see her braided 'do up close.
