What pants look good with a black trench coat?

Have you got any pictures? I want to know what style to match (⊙o⊙)…

Take Han Fan for example, casually wear gray leggings+bright socks (or leggings of various colors directly)+sneakers+a long black silk scarf around his neck? British style? With white shirt+plaid or black, gray and blue cropped trousers+brown socks+retro shoes, street shooting in Europe and America, casual denim shirt with accessories+printed pants? O(∩_∩)O haha ~

Pay more attention to magazines? Or teach the beauty of Weibo and Mushroom Street? Here is a picture for reference.
