It is very important for people with different skin colors to choose the color of clothes. For people with white skin, navy blue and black are ok, but if your skin is yellow, navy blue may be more suitable for you because it can make your skin look brighter. On the contrary, black may make your skin look a little dull.
For people with dark skin, black clothes may make the skin look darker, while navy blue may be more suitable.
The above are just some general suggestions. In fact, everyone's skin color and dressing style are different. The most important thing is to choose the color and style that suits you.
