Nina Dobrev has strict requirements with the men that she dates -- to be with her you will have to be smart, funny and not too vain. Seems easy, right?

Well maybe so, as the Vampire Diaries star opens up in the September issue of Cosmopolitan magazine in which she covers.

"You either have chemistry or you don't, but a lot of what attracts me is a guy's mind and humor and talent. I need to get to know all those things before I fall for someone. I'm not a one-night-stand kind of girl. I'm a relationship girl."

As for how he needs to dress to impress her?

"A man in a suit looking put together and dapper is very attractive, but I also kind of like the I-just-rolled-out-of-bed, a-little-bit-of-scruff, effortless, not-trying-hard-but-still-sexy guy," she says. "If a guy spends more time looking in the mirror than I do, that's a problem!"

As for what she wants?

"People aren't defined by their relationships," Dobrev tells Cosmo. "The whole point is being true to yourself and not losing yourself in relationships, whether romances or friendships."

So who's up for the challenge? Read more of her interview after the jump.
