Invest in a good pair of professional shoes. Think loafers and Oxfords, dark colors and classic lines. Women can wear flats or heels but be sure they are comfortable. 2. Adapt for the season: summer heat can be too much for full traditional interview attire. Whatever the season, you should be dressed to fit in to the work environment. 3. Take your time. Allow an extra hour to get ready to give yourself time to make sure everything, including your hair, makeup and shoe-shine, is perfect. 4. Comfort and confidence are key.  Looking professional and reflecting company culture is important, but feeling certain that you look your best is critical. Wear an outfit that makes you feel confident and comfortable. Relax, be your best, and win at your job interview.
