Purple can be chosen, the Texas Tech Red Raider Country shirt and by the same token and same color with an adjacent color with, the same color with also means with different shades and saturation of purple to match, if it is adjacent color, choose red series and blue series are very good, my video has a lot of matching about purple, can be used as a reference. Black and Navy are a fine combination and they always have been. Black shoes were the preferred footwear choice for navy suits. As someone else pointed out, your complexion could be an issue. If you are very pale, wearing black will exacerbate that. If you have deeper coloring, pulling off black won’t be an issue. A quick tip is that navy works better with more complexions that black will. If you had the opportunity, I would swap the colors, having blue on the top, closer to the face.
