"I think of his character as more old school. He's an older generation, so I love designing the three-piece suit for him, and also the double-breasted suit. It's much more an older generation kind of style. And that's why I love the clubbed colors for him, and that's why he has more accessories. I'll do the beautiful collar pin for him. I love all his accessories. Jon Hamm always wears the French-cut shirt, and so does John Slattery. He has a little more -- if you will -- flair for his costume. I'll accessorize more for Sterling. I think that's also about wealth and personal grooming."
