describe the party at the new york apartment. how does it seem wrong, purposeless?

In contrast to the elegance of Tom's normal life, the party in New York in the apartment which he keeps for his tawdry affair with Myrtle Wilson, is definitely in the low-rent district, especially in the way that the people act. The people certainly have no "class"; they dress flamboyantly, they wear dramatic make up, and they act in nearly amoral ways. Tom does not feel guilty about his infidelity, yet he wants both the "lady" (Daisy) and the "tramp." (Myrtle)
