If you are white, wear a pair of black jeans, which makes you look thinner and more energetic. Of course, other colors are also very good, showing black gray or deep blue. If you want to give others a greater visual impact, you can wear a pair of light-colored pants, which is not bad, but it depends on whether you look good in it. If the skin color is dark, wearing black clothes will look old-fashioned Suggest changing into other clothes.
