People dress casually in everyday life because it's more comfortable and practical. Casual clothes allow for easy movement and are perfect for running errands or just relaxing. They also let people express their personal style without worrying too much about what to wear. Plus, casual clothes are generally easier to maintain and don't require as much time to choose.

At work, people dress formally to project a professional image. Formal attire helps create a uniform appearance and shows competence. It also helps establish authority and respect among colleagues and clients. Many companies have dress codes that employees need to follow, and dressing formally influences how clients and coworkers perceive them.

Dressing formally can create a psychological shift that prepares people for work. It signals a transition from personal to professional life, boosting confidence and focus. Formal attire encourages a sense of responsibility and discipline, helping individuals separate their work and personal lives. This separation is important for maintaining a healthy work-life balance.
