The color of the jacket should be as calm as possible, such as black, gray, Navy blue, coffee, etc., because these colors can overwhelm the overall color
The matching inner cloth clothing can be in the same color or the color next to it. For example, the Navy blue coat can be blue gray, green, blue, gray and other protective clothing, and the black coat is more suitable for matching. However, in order not to make mistakes, it is best to use the old saying of using a unified color scheme.
