Making the right first impression at your interview is easier when you’re confident and calm. Dressing the part always helps. First, err on the side of formality with a suit or blazer, especially for an office or retail position. 2. Avoid distractions like scent, jewelry or statement accessories. 3. Look the part. Visit the store or company website to see how your peers dress. 4. Details count. Obviously, your outfit should be clean and wrinkle-free (we can help with this part). Double-check your résumé for errors, turn off your phone and, if you wear glasses, make sure they too are sparkling clean. Now stand up straight, take a deep breath and good luck.
