A button is small disc- or knob-shaped object attached to cloth or an article of clothing in order to secure an opening, or for ornamentation. A bar is a row of perpendicular hand or machine stitching to reinforce the ends of a buttonhole. A keyhole buttonhole is a worked or machine-made buttonhole with a round hole at the end of the slit to accommodate the button's shank without distorting the fabric; keyhole buttonholes are most often found on tailored coats and jackets. A bound buttonhole's raw edges are encased in a piece of fabric or trim.

A machine-made buttonhole is usually sewn with two parallel rows of machine sewing in a narrow zig-zag stitch, with the ends finished in a broader zig-zag stitch. A worked buttonhole has raw (cut) edges finished with hand sewing, usually in a buttonhole stitch. Pairs of mandarin buttons worn as cuff links are called silk knots.

Flat or sew-through buttons have two or four holes punched through the button through which the thread is sewn to attach the button.

Covered buttons are fabric-covered forms with a separate back piece that secures the fabric over the knob. Shank buttons have a small ring or a bar with a hole called the shank protruding from the back of the button, through which thread is sewn to attach the button.
