Today, Robert is looking at his wardrobe and planning his outfits for the week. The weather is changing, so he needs different materials for different days. Outside, the morning is very cold and windy, so he is choosing a warm wool sweater. He is also putting on thick denim jeans because they are strong and comfortable. Tomorrow, Robert has an important business meeting with his manager at the company. For the meeting, he is wearing a classic cotton shirt and a matching suit jacket. He is also picking up his favorite leather shoes and a matching leather belt. On Friday evening, Robert is relaxing at home and watching a movie. He is wearing his favorite silk pajamas because the material is very soft. Finally, on Sunday, he is going to the local swimming pool. He is packing his nylon shorts in his bag because they dry very quickly.
