Male actors on Thursday dominated the star-studded premiere of "Gangnam 1970," a highly anticipated movie starring Lee Min-ho and Kim Rae-won.

All eyes were on Lee, who wore a diamond-patterned, charcoal waistcoat-and-jacket suit. He chose not to wear a tie and completed his outfit with black and burgundy double monk-strap shoes.

Costar Kim Rae-won appeared in a navy velvet suit with a black T-shirt. In an otherwise toned-down outfit, he also sported crystal-studded black brogues.

Fellow actors Kim Bum, Jung Il-woo and Kim Woo-bin were also in attendance. Kim Bum, who starred alongside Lee in his 2009 breakthrough drama "Boys Over Flowers," wore a casual biker jacket with maroon pants.

Jung Il-woo, friends with the leading actor since middle school, was dressed more casually with gray skinnies, a black duffel coat and a red check scarf.

In contrast, Kim Woo-bin made a somewhat effeminate impression in all-gray outfit with an angora sweater, skinnies and Chelsea boots.

"Gangnam 1970," directed by Yoo Ha, follows the bitter story of petty gangsters against the backdrop of rapid urbanization in Seoul during the 1970s. The film opened in cinemas nationwide on Wednesday.
