What is acceptable to wear in a professional setting is a gray area for many people and businesses. Princeton University breaks it down for aspiring professionals all across America, and defines exactly what “professional dress” and “business casual” entails.
When dressing professionally, men can expect this to mean a suit and tie, while women would wear either a pantsuit or an appropriate dress. Neutral colors are encouraged, and open-toed shoes are not recommended.
Business casual, on the other hand, is not as strict of a dress code. In most “business casual” situations, men will wear dress pants, collared shirts and a belt. Women can wear slacks, or a relaxed dress or skirt, but nothing more than an inch or two above the knee. Blouses must be appropriate, and conservative footwear is suitable. Make note of what your coworkers and supervisors are wearing and observe what has been deemed acceptable and appropriate. Remember, it is always better to be overdressed than underdressed!
