Hayley Atwell made a spectacular entrance at the London premiere of “The World’s End” last night, arriving late and flashing her underpants to the audience.

The actress arrived at the Empire Leicester Square, dressed in a Julien Macdonald transparent sequined dress from his Autumn/Winter 2013 line, Christian Louboutin shoes, and a Jimmy Choo clutch bag.

Atwell impressed in the blue and black design, which featured a sheer back and a plunge in the front.

Unfortunately for Hayley, the entire dress was see-through, and it was obvious which knickers she had selected for the evening.

The Captain America star sparkled even more with the addition of some Maxim Voznesensky pearl gems on her hands and earrings, which were highlighted by her sleek updo.

Thankfully, she was the only one on the red carpet who wore sequins. Star of the film Rosamund Pike wore a contrasting tiny white dress by Victoria Beckham. Cute!

The British actress wore simply a smidgeon of pink lipstick to accentuate her English rose complexion.

Fashion legend Julien isn’t hesitant to expose a little flesh in his creations, and has clothed some of the world’s greatest stars, including Beyonce, Vanessa Hudgens, and Heidi Klum, who also made a fashion faux pas in one of his gowns.

The German supermodel wore a stunning gold sequin gown by the Welsh designer at the 2012 Academy Awards, however the garment had a nip slip.

The World’s End is a comedy of apocalyptic proportions, literally, as it follows a bunch of former childhood pals on a pub crawl of their youth.
