So this new, rich, extravagant life Nick is revealed to triggers a new sense of emotion and he describes it perfectly. He describes the parties Gatsby throws with colorful detail, because he is impressed and overwhelmed. On the other hand, if it was Gatsby describing it, it'd probably be dull because he has experienced them several times and things tend to get less exciting the more you experience them. Nick describes the party with vivid details such as “a fortnights a corps of caterers came down with several hundred feet of canvas and enough colored lights to make a Christmas tree of Gatsby's enormous garden.” (39) and “spiced baked hams crowded against salads of harlequin designs and pastry pigs and turkeys bewitched to a dark gold.” (39-40) Which therefore makes Nick the most suitable narrator. He describes the lavish in Gatsby’s mansion thoroughly the same way he describes the party because, compared to Nick’s cottage, Gatsby’s mansion is a whole other dimension to Nick. He describes even the smallest details that an average person would over look, when he's sent the invitation he describes the courier as, “a chauffeur in a uniform of robin blues” (41). Let's be honest no one else in the book would take the time to take note of the color of a mailman's uniform color. Very descriptive
