How does George's reaction to Beneatha's costume compare with Asagai's reaction to her hair? What does this show about the contrast between the two men?

George, thoroughly confused, addresses Beneatha and asks her to change out of her "costume" and get ready for their theatre date. Beneatha, in a moment of indignation, removes her headdress and reveals to George Murchison her hair in its natural afro state. George is completely shocked. Beneatha seems to have expected this reaction and challenges George's discomfort with her natural hair, accusing him of being "an assimilationist Negro."
