What are the disadvantages of using a zipper in a garment?

Zippers can be prone to malfunction, such as snagging or breaking, which can compromise the functionality of a garment. They may also create bulk or discomfort in certain areas, especially if not properly placed or constructed. Additionally, zippers can be less breathable than other fastening methods, potentially affecting comfort in warmer climates. Lastly, they may require more care in washing and maintenance compared to buttons or hook-and-eye closures.
