Christina Hendricks photographed by James White for Esquire

Mad Men star Christina Hendricks has been named Esquire's best-looking woman in America — and the red-headed beauty has a few words for men.

Hendricks —  who won the title over Megan Fox, Adriana Lima and, yes, Zac Efron with 30 percent of the vote —  graces the cover of the May issue, in which she pens "A Letter to Men" detailing what she really thinks about the opposite sex and what men need to know about women.

"We remember forever what you say about the bodies of other women," she writes. "We will file the comment under 'Women He Finds Attractive.' It's not about whether or not we approve of the comment. It's about learning what you think is sexy and how we might be able to convey it. It's about keeping our man by knowing what he likes."

Women, she says, store away guys' comments about their bodies in the "steel box" as well and love everything about their man's body.

"If we're in love with you, we love your body. Your potbelly, everything. Even if you're insecure about something, we love your body," she says. "You feel like you're not this or that? We love your body. We embrace everything. Because it's you."

Hendricks is also impressed by manners ("stand up, open a door, offer a jacket") and those with a fondness for Scotch. "It's classic. It's sexy. Such a rich color. The glass, the smell," she says. "It's not watered down with fruit juice. It's Scotch. And you ordered it."

While the 34-year-old encourages the use of the word "panties," she does not want guys in tank tops — which she calls "underwear."

Also a big no-no: being on Facebook. "It's an invasion of everyone's privacy," she says. "I really cannot stand it."

Mad Men's Christina Hendricks gets married

The actress, who wed actor Geoffrey Arend in October, adds that marriage doesn't change much. She says the qualities that matter most are still "intelligence and humor (and your smell)."
