"The World's End" premiered to a celebrity crowd at London's Empire Leicester Square on July 10. "The World's End" gang, led by Rosamund Pike, Simon Pegg, Nick Frost, Martin Freeman, and Director Edgar Wright got all dressed up for their walk on the blue carpet.

Rosamund wears a Victoria Beckham dress.

35-year-old actress Rosamund Pike was a stylish vision in white. The British actress looked chic in a Victoria Beckham sheath dress. The sleeveless number came in Posh Spice's trademark body-conscious silhouette. At first glance, Rosamund's pick seemed like a prim, at-the-knee dress choice. However, a second glance reveals a shock of hot pink - Rosamund's bra seen through her dress' front lace panel. More revealing lace panels on either side of the dress balanced that high, demure neckline. Rosamund expertly echoed her wink of hot pink with a fabulous pair of nude-and-pink Elie Saab t-strap sandals. What a delightful outfit from the "Wrath of the Titans" actress.

"Downton Abbey" star Michelle Dockery joined the star-studded premiere for the comedy film. She wore a casual outfit on the blue carpet. It was a pair of skinny black trousers, black pumps, and a silk top for Lady Mary on this occasion. Michelle looked relaxed in her loosely fitted, blue blouse with a muted floral print.

Also joining the fun at "The World's End" World premiere were "Britain's Got Talent" judge David Walliams and actresses Alexandra Roach and Ophelia Lovibond. Ophelia, who is set to star in "Guardians of the Galaxy," served a charming retro look. Her white, puff-sleeved shift dress, paired with playful feather embellished heels made for a winning look. Sadly, Alexandra Roach's red-and-green printed top and wide-leg pants did not do her any favors.
