If you don't like black all over, I personally think red, white and silver will do. With black, it is very classic.
No matter what color you choose, the key is the color of shoes and the color of bags (if you choose belts, the colors of belts should be uniform). In addition, ornaments only play the role of finishing touch, and one or two pieces are enough, so don't ask for more.
I found a Dior here for your reference. It doesn't matter if the style is different, the key is the effect of color.
