Whoever coined the phrase "Cheaters never prosper" clearly never met Yunjin Kim. The South Korean–born actress has carved out a nice career playing women involved in various forms of hanky-panky. On the hit series Lost she two-timed her husband with her English tutor. And this summer Kim is streaming things up on ABC's Mistresses (Mondays, 10/9c), a deliciously irresistible drama about four friends entangled in extramarital mischief—though, she points out, a lot of the intrigue takes place outside the bedroom. "The show isn't just a bunch of home wreckers having tons of sex," she says. "It's more complex than that." For our August issue, we caught up with the actress and asked her to model some of the most tempting looks of the season. This photo here, shot by Phil Poynter and styled by Kate Sebbah, is just a preview of what you can expect. Pick up the new Olivia Wilde-covered August issue -- or download it on your tablet -- to see all of the exclusive photos and get the star's "Cheat Sheet" to the fine art of sneaking around. Hint: "Co-workers should be off-limits," says Kim.
