Keep in mind that skills listed for the career are not restrictions for the character.
As alluded to, Fops aren't known for being particularly skilled. They (stereotypically) tend to rely on wealth or personal charm to have others do what they need done.
Just because it only has 4 skills and most others have 5 does not mean that the Fop needs to be changed or somehow "make up" for the lack of the additional skill. It all comes down to character and the story. The Fop is an idle wastrel. The player should play it up and revel in the fact that he has no real skills, but has a lot of daddy's money/influence to throw around.
