"Blue Bloods" is not your average cop show. Yes, it has the customary crime-solving plots, but it also delves into the personal lives of its characters. One way the show accomplishes this is through the weekly Sunday dinners of the Reagan family. These dinners bring the entire cast together and serve as a highlight of each episode.
The family's patriarch, Frank, played by Tom Selleck, particularly cherishes these dinners. He takes his seat at the head of the table, engaging in lively conversations and occasional arguments with his family. But there's something unique about Frank during these dinners – he almost always wears a sweater, regardless of the season.
Observant fans of "Blue Bloods" have pointed out that Frank has a penchant for old-fashioned fashion choices. And while Tom Selleck has not commented on this wardrobe choice, it is likely attributed to Frank's traditionalist nature. He is a man who values duty and professionalism, and his Sunday dinner sweaters perfectly balance casual and put-together attire.
The concept of the family dinners in the show was inspired by a Norman Rockwell painting, according to producer Leonard Goldberg. This Americana feel is further emphasized by Frank's love for sweaters, adding to the comforting atmosphere of "Blue Bloods" even amidst the compelling crime narratives it explores each week.
