First, if you have a moderate figure and good looks, then look down.
Second, if you choose slim jeans (including straight jeans, slim jeans and bell bottoms), you should divide them into light dark jeans and light jeans. You should choose a shirt with fresh colors or a little pattern, and don't be too conspicuous (unless you are a model). Of course, you can choose right-angle jeans or dovetail jeans. But you should pay attention to one principle in the choice of coat, that is, it fits well and won't make you feel uncomfortable. If the top is just right and the figure proportion is moderate, the front half of the boxer shirt can be slightly tucked in front of the pants, and the dovetail shirt can be a little more casual. But here we can consider a principle. If you have a sexy figure, you can wear a versatile belt or a popular belt. If you are not of this figure, you can choose some belts with medium appearance. There is also a classic collocation of light-colored jeans, that is, a black shirt, but it is best to choose bright chemical fiber or a black shirt with different attributes as the material of the shirt. You can choose a variety of colors for your belt, but you must use bright metal buckles.
Thirdly, if it's wide jeans (skateboard, small, Korean version), then the shirt you choose must be another type, regardless of the color, depending on the color at the bottom, and other accessories should be complete, otherwise it will not reach the proper taste/
Fourth, follow the second rule. If you use the type mentioned in the second rule and the color is dark, you will feel better with T blood. However, you can also consider a plaid shirt with a moderate color. Remember, colors should not be too outdated, and the changes should be significant. Otherwise, the top will be eclipsed by the dark color at the bottom. Only by exaggerating the color and style of the coat can we achieve overall coordination.
In short, the collocation of clothes is very particular. Go shopping more and try on clothes more. In that case, you will have more and more experience:)
