Royal blue is a very bright color, so don't match other colors in the lower body to avoid color grabbing. Dressing should be focused and the top should be prominent, so it is best to wear black and white on the lower body. Blue and white jump, clear. Blue and black fashion, see what style you like. Hehe, as for shoes, it's best to match the color of pants. Of course, tight pants are better, and it would be more perfect if they were high-gloss metal.
