This is the text (if you need help).
More companies are letting staff dress casually. Staff don't have to wear a suit and tie. Companies want staff to feel relaxed, so they work harder. The bank Goldman Sachs wants its workers to "exercise good judgment" in deciding what to wear. It said workplaces are becoming more casual.
Some people think casual is not good. People might think the company is not serious. One boss said a suit gives a good image. He said: "You're looking after people's money, so you should...dress [well]." He said it would be dangerous to give money to someone in jeans. Companies like Google let workers wear jeans.
Back to the business suit lesson.
