So, what is a dress code?

This is what you’re looking for what you’re doing your homework. For example, you might hear that a company is “business professional.” But what's the difference between business professional and business casual? What happens if a company describes its dress code as “casual,” how do you know what’s too casual? Here's some insight to understanding what some of the most common office dress codes really mean:

• Business professional: This is an environment where suits are the norm. Women might wear a skirt or pant suit with heels. Men are expected to wear a suit and tie.  Men might be able to wear a sports coat, button down dress shirt, dress pants, a tie and dress shoes.  It’s best in this setting to overdress first and learn the rules before wearing a more casual sports coat and complementary dress pants.
• Business casual: You’ve got to forget the suit when interviewing at a business casual company. Men might opt to wear dress slacks or chinos, a button down or polo shirt, a belt and dress shoes. Women might consider wearing a conservative dress, or a blouse (or sweater) with a skirt or dress pants and dress shoes or boots.
• Casual: When interviewing at a casual office, you’ll still need to look polished and professional. The most important thing here to consider is the quality of what you’re wearing not the item itself. Also, save the jeans and flip-flops for when you actually have the job.  Men might consider wearing a long-sleeved dress shirt, khaki pants a belt, and dress shoes. Women might wear a collared shirt with pants or a pencil skirt, or a work dress.
