Silver buttons were an important element of traditional dress in Spain. Unlike in most other European countries, women were just as likely to wear them as men. Both sexes wore them in extravagant quantities, along the seams of jackets and trousers and in bunches at the wrist, as well as to fasten clothes. Although filigree buttons were the most typical, many regions used buttons made of sheet metal as well.
They were rarely sewn directly on to the clothing. In some places people fastened them to their costume with a strip of leather, which ran through the button loops inside the garment. More commonly they used T-shaped toggles permanently attached to the button.
The shape of these buttons is unusual, but Spanish toggle buttons were made in a great variety of patterns.
