Business casual attire for men and women is crisp, neat, and should look appropriate even for a chance meeting with a CEO. It should not look like you are dressing for a cocktail party, going out to a night club or headed to a picnic. Avoid tight or baggy clothing.
What is most important is to represent your true self - your culture, your personality, your comfort - but in a polished way. This shows respect to the organization and the people you are meeting, and shows your care for yourself.
Khaki pants, and a long-sleeved, buttoned solid shirt are safe. Jacket, blouse, cardigan or conservative top with pants, or knee-length skirt works as well. Polo/golf shirts are appropriate if the environment is casual, outdoors or in a very hot location.
Wear a leather belt and leather shoes. Athletic shoes are inappropriate. If you choose to wear jewelry, be conservative.
Clothes should be clean, neatly pressed, and fit properly, neither tight nor baggy. There shouldn’t be missing buttons or lint; and remove external tags and tacking stitches from new clothes. Shoes should be in polished condition. Make sure heels are not worn.
If you are wearing a new outfit for an interview, practice walking and sitting in your interview outfit, including shoes, to check fit and necessary range of movement.
Hair should be clean and neat, fingernails need to be clean, perfume or cologne should be used sparingly or not at all. Keep make-up subtle, natural. Keep facial hair trimmed, shaped and well maintained.
Appropriate to carry to an information session held on campus (after all, you are a student). For career fairs and job fairs, bookbags are generally checked at the door, and you should carry a padfolio only.
