People of different ages usually dress in different types of clothes.
Young children now wear fun and comfortable clothes so they can run, jump, climb and play.
Look at Daniel. Imagine him dressed like a Dad going to the office. When your grandparents were young, he would have been dressed somewhat like that. Do you think it would be fun to dress like that? Do you think it would be comfortable for playing?
Older children, or teenagers, like to choose their own clothes. They like to go shopping.
