If you have a belly, it is recommended to wear a transparent stainless steel belt buckle with an inclined shaft in the middle, which has two advantages: first, the belt can inhibit the belly from sagging and getting bigger; Secondly, such a belt is more convenient to loosen, the vertical shaft is easy to break after a long time, and it can't be untied in an emergency, which will bring a lot of trouble. If you consider it from a good-looking point of view, it depends on the form of belt buckle. It is generally better to choose a thicker and brighter belt buckle. If the clothes are dark, you can choose a lighter or darker belt buckle. I hope these suggestions will help you!
