Grooming tips for everyone: 

• Hair:
  Should be clean and neat.
• Shoes:
  Should be in polished condition. Make sure heels are not worn.
• Details:
  No missing buttons, no lint; and don't forget to remove external tags and tacking stitches from new clothes.
• Hands:
  Clean fingernails.
• Fit:
  Clothes should be clean, neatly pressed, and fit properly.
• Smell:
  Perfume or cologne should be used sparingly or not at all. No odors in clothes. Don't smell like smoke.
• Pad folios:
  Preferred over a bulky briefcase. A small briefcase is also appropriate. But if you have no reason to carry a briefcase, don't; you risk looking silly.
• Book bags:
  Leave it at home for an on-site interview. For an on-campus interview, you can leave it in the waiting area.
