Dress Codes Deciphered

It's your first day at your new job. Your new boss told you the dress code at your new company is ''your standard business casual.'' That sounded simple enough at the time, but now, as you stand wearily in front of your closet, you're at a complete loss. You don't think you should wear a suit, but are khakis appropriate? Do you need to wear a button-down shirt and tie? How about a polo shirt?

Whether you're just starting out in the working world, starting a new job or simply moving to another department or position, figuring out a new dress code can be a real gamble. Business casual... executive casual... mainstream casual... what's the difference?
