In George Bernard Shaw's "Man and Superman," the quote highlights the importance of adaptability and understanding individual changes. The speaker points out that only their tailor recognizes the need to take new measurements, suggesting that this attention to detail is crucial for a fitting outcome. This reflects a broader theme of how individuals often fail to consider personal growth and change in themselves and others.

Moreover, the statement critiques societal expectations, where people cling to outdated perceptions and stereotypes. While the tailor adjusts his approach, others maintain rigid views, leading to a disconnect between expectations and reality. This commentary encourages readers to embrace flexibility and recognize that everyone's experiences and circumstances evolve over time.
