Now, obviously, both Christina Hendricks and Elisabeth Moss are extremely lovely ladies. But their characters on “Mad Men” have colored how they are perceived, and the general thinking is that Joan is hot, hot, hot while Peggy is a little frumpty-dumpty. So I was thrilled to see Elisabeth turn the glamour up to 11 at last night’s “Mad Men” season four premiere in a killer green, one-shoulder dress. Meanwhile, Christina wore a black number that felt just a little too covered up and gothy for her. Who’s hot now? That’s right—both of ‘em.
