The "business professional" dress code is formal and conservative. It is traditionally worn by executive or "white-collar" workers to give the impression of competence.
For women, this dress code might include a slim cut pantsuit, skirt and jacket with dark tights, or a structured, yet conservative dress. Clothing should be well-fitting but not tight, and colors are typically muted.
Men traditionally wear dark suits; black, navy or charcoal are common, along with black or brown formal shoes such as Oxfords. Shirts are typically white or another pale shade, while ties are largely down to personal taste, ranging from the flamboyant to the dull.
