The fact that Gatsby replaced this woman's dress represents a man of compassion and sincerity. Although he buys this dress with no consent to the money spent, it shows that Gatsby cares about those who attend his parties. Lucille mentions prior, " 'I never care what I do, so I always have a good time' " :symbolizing another East Egger and her careless wealth (25). .
On the other hand, Gatsby and Buchanan's temper are very opposite. Tom is introduced in the novel as an arrogant and rich man who develops a sense of complete selfishness, racism and sexism. Hard cruelty is shown in Mr. Buchanan when he discusses his attitudes towards the superiority of the white race as well as his secret affair with Myrtle Wilson. "Making a short deft movement, Tom Buchanan broke her nose with his open hand" (39). Myrtle speaking of Daisy's name was enough to enrage this "hulking" man, as Daisy describes Tom (17). To add, Jay Gatsby appears as a more approachable, harmless man. Jordan Baker recounts how one morning in 1917 she met Daisy and an unknown admirer, a military officer, who watched Daisy "in a way that every young girl wants to be looked at" (75). By looking at Daisy in this loving, admirable way, Jay reveals his tender and affectionate personality. .
Not to mention, Tom and Jay's social aspects contrast as well. Tom enjoys low key and almost 'secret' parties with his mistress, whereas Gatsby is very showy and vibrant with his extravagant parties that he host's every weekend for nearly all of New York to enjoy. This evidence is shown in the following quote: "The bar is in full swing, and floating rounds of cocktails permeate the garden outside, until the air is alive with chatter and laughter, and casual innuendo and introductions forgotten on the spot, and enthusiastic meetings between women who never knew each other's names" (42). Gatsby and Tom are different considering their wealth, temper and social aspects.
