"Nothing earth-shattering has happened in men's fashion. How much can you do with men's clothes?"

In this quote, Calvin Klein is revealing his opinion on the state of males's style. He thinks that there have actually not been any substantial changes or groundbreaking developments in the world of males's style. He questions the potential for innovation and creativity in designing guys's clothing, indicating that there might be limitations in this area. This declaration could also recommend that men's fashion is not as dynamic or interesting as women's fashion, which typically sees more experimentation and evolution. Overall, Klein's words convey a sense of uncertainty and perhaps even disappointment in the existing state of guys's fashion.
