"Extended Family" on NBC is a comedy that explores the dynamics of a modern family navigating divorce and child-sharing. The show centers around Jim and Julia, a divorced couple who choose to raise their kids together in the family home, alternating their stays. The plot thickens when Trey, the owner of the Boston Celtics, becomes romantically involved with Julia. Fashion plays a significant role in the show, with Julia, the main character, sporting trendy yet age-appropriate designer outfits. Her daughter Grace contrasts this with a more casual and youthful style.
