A black shirt worn with khakis is perfectly acceptable. Many style experts now encourage combinations of khaki, black and brown as well. Contemporary standards have more to do with balance and personal style than the old bans on color mixing.
The appropriateness and appropriateness of color combinations have as much to do with the types of clothing involved as the colors. A black polo shirt with khaki pants can overwhelmingly suggest a trip to the golf course, but a sleek button-down shirt in cotton or linen creates a more sophisticated impression. Khaki and black are both technically neutral. Making the primary and the other attractive is interesting, suggests Global Post. Adding a third accent color that balances the two brands for an even more elegant look.
