What to Wear to a Job Interview ‣ Always wear a collared shirt, whether it’s a button-down or a polo. No need for neckties here. ‣ Do not wear denim. Put on some khakis, chinos, or some other pair of medium-weight slacks. ‣ Putting on a jacket or blazer is a good way to show that you’re dressed for success in the workplace. ‣ Shop floor footwear should have a strong sole to prevent slips and falls.
