What should you wear to a job interview? Dressing for a job interview means putting your best foot forward, and wearing professionally appropriate clothing. The first impression is the most important one you make, particularly with a future employer. For better or worse, what your potential employer sees the first time he or she looks at you will form their very first ideas about you. You won’t have a second chance at this, so plan carefully and dress appropriately. Of course, when you interview successfully, your clothes won’t be the only thing that your future employer remembers. But don’t let poor wardrobe choices ruin what could otherwise be a great interview.
