For a job interview, wear clean, simple clothes. Your clothes should fit you well. Check them for holes, hair, and dirty marks. A shirt and dark pants are often safe. A simple dress can also work. Wear clean shoes. Do not use a lot of perfume. Before the interview, see what workers wear. You can also ask, “What should I wear?” (dol.gov)

For example, you want a café job. The workers wear T-shirts and pants. Choose a clean shirt for your interview. Wear simple pants and clean shoes. You look ready and feel good.
