Here are some ideas of what to wear to your interview. How you should dress will vary somewhat depending on the industry and specific company culture, but it's better to dress up than to be too casual.

• Unless otherwise directed, dress conservatively. Men should wear a dark suit and conservative tie. Women should wear a dark suit​. Avoid miniskirts, trendy outfits, or loud colors. However, for a more casual or part-time position, it may be appropriate to wear a collared shirt, slacks, and/or a polo shirt.
• Make sure your clothes are cleaned and pressed.
• Wear polished conservative shoes with closed toe and heel. Men should wear long, dark socks and women should wear trouser socks or if wearing a skirt, tights or nylons.
• Minimize jewelry, makeup and fragrance. Women should wear no more than one pair of small earrings. Men and women should wear no additional body piercings.
• Style your hair neatly and keep it off your face.
