v. fasten with buttons; be fastened with buttons

In clothing and fashion design, a button is a small disc- or knob-shaped, typically round, object usually attached to an article of clothing in order to secure an opening, or for ornamentation. Functional buttons work by slipping the button through a fabric or thread loop, or by sliding the button through a slit called a buttonhole.
