A button for clothing is a small round thingy that is sewn onto the fabric of your shirt, pants, jacket, or dress. It can be made of different materials like plastic, metal, or even wood. Buttons help close up the shirt or dress so it doesn't fall off your body. When you pull the button through a hole in the fabric, it helps keep the fabric together so you don't have any open spaces that would show your body. Buttons also come in different colors and designs to make your clothes look pretty and stylish!
