Jon Hamm and Colin Firth are two of the classiest actors in Hollywood.
But it's time for these veteran stars to get down and dirty! You've gotta take it to the limit when competing in a Fashion Face-Off, as Hamm should not be afraid to mock Firth's stutter, or Firth be scared to call Hamm out for his drinking and womanizing problems.
Nothing is off limits when fashion honors are on the table, gents! Have at it now. May the most handsome win.
