Look at the height
Regardless of whether it is a skirt or a jacket, the height of both sides of the zipper must be the same, and the color of the zipper and the fabric must be the same. Sometimes due to unreasonable sewn zipper capacity, it will easily cause unevenness on both sides of the waist.
Look at the buttonhole
The buttonhole is pointed at one end and round like a cone at the other end. It must be shipped by a professional clothing factory, and the cost is obviously much higher. If the ends are sharp but the sutures are tight, the quality is okay.
High-end men’s shirts will make the penultimate buttonhole or the second buttonhole horizontal to prevent the buttonhole from breaking when sitting down due to too big belly.
Look at the zipper
The prerequisite for a good zipper is that it can be pulled up smoothly, can be flat against the body, and will not bulge. At the same time, the zipper must be able to be completely locked at the top, and will not slide open just because you lift the surrounding fabric. Metal zippers are more durable than plastic zippers, and plastic zippers are more easily damaged. Plastic zippers are generally used for cheap clothes.
