Navy blue and black match and work well together, according to Global Post. While wearing navy and black together has often been considered a fashion faux pas, style experts assert that it is acceptable to wear the colors together.
Global Post recommends choosing the right shades of navy and black. For example, it is not appropriate to combine shades of navy and black that are difficult to distinguish. The key to wearing navy blue and black together is to create a noticeable contrast between the two colors. Mixing up textures and breaking up the colors with a different colored belt or accessories provides a suitable end result.
