In ancient Rome, the initial buttons were used to make ornaments, and the clothes used pins. In the 13th century, the role of buttons was the same as today. At that time, people had understood how to open buttonholes on clothes. This approach greatly increased the practical value of buttons. In the 16th century, buttons were popularized.
In medieval England, the shirt was first invented, the button on the woman's shirt was on the left, and the button on the man's side was on the right. The reason was that aristocrats needed maids to wear clothes when they got up early, while men wore their own clothes.
In the sixteenth century, the Chinese transmitted the buttons to Europe. At that time, only men used them, and there were fewer female users. Most people used them only as clothing. In order to show their wealth, some Daguan nobles use precious gold, silver, pearls, precious stones, diamonds, rhino horns, antelope horns, and precious materials of ivory to make buttons. King Louis XIV of France has used 13,000 precious buttons to make a royal robe. In my current collection, precious horns, antelope horns, ivory, precious gold and silver precious materials are used.
We often say 14#, 16#, 18#, 20#, 60# and so on! Its changing formula is: diameter = model * 0.635 (millimeter). If we have a button in our hand, but we do not know its size, we can use a caliper to measure its diameter (mm) and divide it by 0.635.
There is another way to express the size of the button: L
The conversion relationship is as follows:
Button size:
1L=0.625MM 1MM=1/25 inch INCH) Representation method unit: L, number (LIGNES)
12L=7.5 MM=5/16" 13L=8.0 MM=5/16" 14L=9.0 MM=11/32"
